How to freeze
Remove from the tin and open freeze, then transfer to a freezer bag. Defrost, then reheat in the microwave.
Heat the oven to 200C/180 fan/gas 6. Grease 6 holes of a muffin tin. Put the carrot, courgette and peas (about 190g veg) in a microwaveable dish with 2 tbsp water. Cover with cling film and cook for 2 mins or until tender. Drain the veg.
Beat the eggs and stir in the veg and feta. Pour into the 6 holes. Bake for 15 minutes until the eggs are set. Leave for a minute or two, then use a knife to carefully remove the ‘muffins’.
