Half tsp any oil - I like rapeseed or olive oil
Half a small courgette (zucchini) grated
1 medium carrot grated
6 cherry tomatoes quartered
1 tbsp frozen peas
2 eggs beaten
Warm the oil in a small frying pan and add the courgette and carrot. Stir on a medium heat for 3 to 4 minutes.
Add the tomatoes and peas, stir and heat for a further minute or so.
Add the eggs and cook slowly until the eggs are firm - about 5 minutes or so depending on the size of your pan (smaller pan makes frittata thicker so takes longer). If you're in a hurry you can pop under the grill to finish cooking the top.
Leave to cool then cut into bite sized chunks.
Other things we put in sometimes are onion, peppers, sweetcorn, boiled potato, broccoli, kale or spinach (chopped into tiny pieces), grated cheese, chicken, turkey, tuna, salmon, sardines, anything you like really.
