This recipe breathes life into vegetable peelings, smoked fish or leftover roasted vegetables. As you make the base, keep an eye on the “zero-waste it tips” below for chances to spruce up your pan with some delicious leftovers!

Serves 2-4


1 tbsp coconut or olive oil
1 onion, about 85g (3oz), finely chopped
3 garlic cloves, crushed
50g (1¾oz) spinach, tough stalks removed, chopped
100g (3 ½oz) broccoli florets, stem, and leaves, finely chopped
50g (1¾oz) peas, fresh or frozen
6 eggs
150ml (5fl oz) milk, nut or dairy
2 tbsp fresh chopped herbs such as parsley, dill, chives or thyme
75g (2½oz) cheese, such as feta or Cheddar, crumbled or grated (optional)
salt and freshly ground black pepper

Preparing the base:

1. Heat the oil in a medium, non-stick, ovenproof frying pan over a medium heat.

2. Add the onion and garlic, and cook slowly for 3-4 minutes until soft.

3. Add the vegetables and cook for a further 4-5 minutes.

4. Whisk the eggs and milk together. Stir in the herbs and cheese, if using, then season with salt and pepper to taste.

5. Preheat the grill on a medium setting.

6. Level out the vegetables in the pan and gently pour the egg mixture over them. Reduce the heat to low-medium and continue to cook the frittata for 10-15 minutes, without stirring, until the underside is cooked.

7. Place the pan under the grill for about 5 minutes to set the top of the frittata.

8. Remove the frittata from the grill and allow to cool for 2-3 minutes before serving.

Zero-waste tips:

Vegetable peelings

Replace the spinach with 100g (3½oz) mixed vegetable peelings, such as carrot, beets, parsnip, or potato, and add to the frittata at step 3 with a splash of water. Increase the cook time at step 3 to 10 minutes.

Smoked fish

Add 150g (5½oz) of leftover ready-to-eat smoked fish, skinned and broken into bite-sized pieces, at step 6.

Leftover roasted vegetables

Replace the spinach, broccoli and peas with around 300g (10oz) leftover cold roasted vegetables. Chop into small cubes if necessary, and add to the frittata at step 3.
