Eat leftovers once a week
Small acts are all it takes to make a big impact
Food waste comes at a big cost, both for your bank account and for the planet. But you can reduce food going to waste – and save yourself precious time and money – simply by planning to eat leftovers once a week.
It’s a small act with a big impact on Victoria’s sustainable future.
Why it matters
Food waste in Victoria
- Each year, Victorian households throw away 250,000 tonnes of edible food – enough to fill Melbourne’s Eureka Tower.
- The average household in Victoria throws away $2,600 a year in wasted food.
- Almost two thirds of the food Victorian households throw away could have been eaten.
(Sustainability Victoria, Path to Half Report, 2020)
The environmental impact
Food thrown into your general rubbish bin ends up in landfill. Food in landfill breaks down in a way that creates greenhouse gases, including methane, which affects air quality and public health. When we waste food, we also waste the resources used to grow our food (water, soils and energy) and all the energy used to process, package and transport food from farms to markets to our homes.
Tips and tricks
Give your leftovers a makeover
There are lots of creative ways to use up leftovers:
- Make croutons from stale bread to add crunch to a salad or soup or whizz it up into breadcrumbs (use in schnitzels, meatballs or vegetable bakes).
- Use roast meats or deli meats and cheeses to make a tasty toastie.
- Toss chopped vegetables into a simple stir-fry or hearty stew.
- Blend overripe fruits into a smoothie or use them for baking.

Get organised
Planning meals, shopping smart and storing food correctly can help you reduce food waste and save money.
Organise your pantry, fridge and freezer so it’s easy to see food that needs to be eaten.
Plan ahead
Before you go food shopping, check what you already have and plan a meal that combines ingredients that need to be used.
When planning meals for the week, try to choose recipes with similar ingredients. Need half a tub of cream on Monday? Plan a dish that needs the other half for another day.
Store food right
Find out how to store fresh produce so that it lasts until you’re ready to use it. It is possible to keep celery and carrots crunchy.
After cooking, store leftovers in well-sealed, clear and labelled containers. Freeze any portions that will not be eaten within the next 3 to 4 days. Then enjoy them when you need a night off cooking or a grab-and-go work lunch.

Raspberry, oat and banana muffins
When bananas begin to soften, they are at their best for baking – sweet and easy to mash. Here I use them in some simple muffins which are perfect for school lunchboxes. I like to use frozen raspberries but whatever frozen berry you have in the freezer is perfect – blueberries, strawberries and blackberries are all great.
Makes 12 small muffins.
Ingredients
125 g raw caster sugar
2 eggs
1 tsp vanilla extract
150 ml light flavoured extra virgin olive oil
3 very ripe bananas, mashed (around 400 g)
100 g rolled oats, plus extra for topping
150 g self raising flour
1 tsp ground cinnamon
150 g frozen raspberries
Instructions
Preheat the oven to 180°C. Line a 12-hole muffin tray with patty pan cases or simply grease the tray.
In a large bowl whisk together the sugar, eggs and vanilla. Pour in the extra virgin olive oil and whisk until well combined. Add the mashed bananas and whisk well. Add the rolled oats, self raising flour and ground cinnamon and whisk until just combined. Fold through the raspberries.
Spoon the batter into the patty pan cases and top with some extra rolled oats.
Bake for 25 to 30 minutes or until the muffins are cooked when tested with a skewer. Allow to cool briefly in the tin then transfer to a wire rack to finish cooling.

A simple lemon yoghurt cake which is perfect for afternoon tea and is a great way to use up excess yoghurt in the fridge. It stays moist for quite a few days thanks to the extra virgin olive oil and is bright and zingy. I’ve made an easy lemon glaze to top the cake. I’m always looking for ways to use up herbs, so here the cake is topped with some thyme leaves which adds some interest to this simple cake.
Serves 8 to 12.
Ingredients
3 lemons
250 g caster sugar
3 eggs
150 ml light flavoured extra virgin olive oil
200 g Greek yoghurt
250 g self raising flour
Lemon icing
150 g icing sugar
Juice of a lemon, as needed
Fresh thyme sprigs, to serve
Instructions
Preheat the oven to 180°C. Grease a 24 cm bundt cake tin.
Finely zest the 3 lemons and juice 2 of them (you should have 100 ml of juice). Reserve the third lemon for the icing. Set aside.
In a large bowl, whisk together the sugar and eggs until well combined. Add the extra virgin olive oil and whisk well, followed by the yoghurt. Add the lemon zest and juice and whisk to combine.
Add the flour and gently whisk until just combined. Pour the batter into the tin and bake in the preheated oven for 40 to 45 minutes or until a skewer comes out clean when tested. Allow to cool for 10 minutes in the tin, then invert onto a wire rack to finish cooling.
For the icing, whisk the icing sugar in a medium bowl with enough lemon juice from the reserved lemon to create a thick but pourable icing. Drizzle onto the cooled cake, top with thyme and allow to set before serving.

When I have leftover roasted cauliflower, I love turning it into a satisfying salad. Here I’ve detailed how to roast cauliflower too, which is also handy when you have cauliflower in your fridge that needs using up. Whichever route you go down, it’s a great midweek salad for lunch or a light dinner. I’ve used Moghrabieh or pearl couscous, but any grain is lovely here. Feel free to use whichever herbs you have on hand.
Serves 4.
Ingredients
500 g (around half a head) of cauliflower broken into florets
4 tbsp extra virgin olive oil
1 tsp baharat spice
Sea salt, to taste
1 onion, halved and sliced
1 bunch silverbeet (around 300 g), washed and roughly chopped, including stems
150 g Moghrabieh (pearl couscous)
Large handful each of parsley, coriander and dill, roughly chopped
50 g raisins
50 g pine nuts or slivered almonds, toasted
Pomegranate dressing
1 tbsp extra virgin olive oil
Juice of a lemon
1 tbsp pomegranate molasses
1/2 tsp brown sugar
Instructions
Preheat the oven to 180°C. Line a baking tray with baking paper or a silicone baking mat.
In a bowl combine the cauliflower with 2 tablespoons of the extra virgin olive oil, baharat spice and a generous pinch of salt. Toss to combine and tip onto the prepared tray. Arrange in a single layer and roast for 30 minutes or until golden and cooked through. Transfer to a large bowl and set aside.
Meanwhile, warm the remaining extra virgin olive oil in a large frying pan over a medium heat. Cook the onions with a pinch of salt until soft and beginning to colour, for around 10 minutes. Add the washed and still damp silverbeet to the pan and cook for 15 minutes, or until the silverbeet is very soft. During the cooking, add a little water to the pan to avoid it drying out. Add to the bowl with the cauliflower.
Cook the Moghrabieh according to the packet directions, drain and add to the bowl along with the herbs, raisins and pine nuts or almonds. Toss to combine.
For the dressing, simply combine all ingredients together in a jar, season with salt and shake to combine. Pour onto the salad and mix well. Check for seasoning and serve warm.

This is the perfect recipe if you have some potatoes in the pantry that are no longer looking their best. Simply peel and boil them for mashed potatoes and use them in these irresistible pancakes. It’s also a wonderful way to use up leftover mashed potatoes from the night before. I’ve chosen hot smoked trout to serve with these pancakes, but also bacon is tasty. Or keep it vegetarian and top simply with some watercress or roasted tomatoes.
Makes 10 pancakes.
Ingredients
500 g potatoes such as Desiree or Dutch Cream, peeled
60 g butter, melted, plus extra for cooking
2 eggs, lightly beaten
1/2 tsp finely grated nutmeg
Bunch of chives, finely chopped
Salt and pepper, to taste
125 g self raising flour
Extra virgin olive oil, for cooking
Hot smoked trout, flaked, to serve
Crème fraîche, to serve
Instructions
Quarter the potatoes and place in a saucepan. Cover with cold water, season with salt and cook for around 20 minutes or until soft. Drain and press through a potato ricer or mash in a medium bowl. To the potatoes, add the warm melted butter and mix to combine. Add the eggs, nutmeg and most of the chives, reserving some for serving. Season well with salt and pepper. Add the flour and gently mix until just combined.
Heat a frying pan over a medium heat. Add a little extra virgin olive oil and a knob of butter and when foaming, scoop in 1/3 cup of the mixture. Work in batches to not overcrowd the pan. Cook the pancakes for 4 to 5 minutes, flipping halfway and slightly pressing down with a spatula, or until golden and cooked through.
Serve with hot smoked trout, crème fraîche and extra chives.

Inspired by Okinawan taco rice, usually made with minced beef, this version makes use of leftover steak which simply needs warming through the onions and spices before being served. I have suggested the classic toppings but feel free to play around with them – salsa, coriander or cabbage would also be delicious.
Serves 4.
Ingredients
2 tbsp extra virgin olive oil
1 brown onion, sliced
Sea salt
1 tsp ground cumin
1 tsp ground coriander
1 tsp smoked sweet paprika
2 tsp dried oregano
1 tbsp soy sauce
60 ml chicken or vegetable stock
300 g leftover steak, sliced
12 5g cherry tomatoes, halved
1/4 iceberg lettuce, shredded
1 red onion, finely sliced
125 g cheddar cheese, grated
1 spring onion, finely sliced
Steamed Japanese short grain rice, to serve
Instructions
In a large fry pan over a medium heat, warm the extra virgin olive oil and add the onion with a pinch of salt. Cook for 10 to 12 minutes or until soft and beginning to caramelise. Add the spices and dried oregano and cook for 2 to 3 minutes or until fragrant. Add the soy sauce and stock and simmer until almost reduced. Add the steak to warm through.
Spoon steamed rice into four bowls and top with the steak, some cherry tomatoes, lettuce, onion, cheese and spring onion.
