Heat the oven to 180 degrees celcius or 160 degrees celcius if you have a fan oven

Oil a muffin tray REALLY well or alternatively use muffin cases. It's really important to oil the tray well or if you are using muffin cases to get the ones that will not stick

Whisk the eggs and the plant-based milk - we have used almond milk.

Add the chopped tomatoes and spinach and salt to the egg mixture and combine well.

Pour the mixture into the muffin tray. You should have enough for 6 regular muffins.

Cook for between 25 and 30 minutes or until the centre is not wobbly. Remove from the oven and let it rest for 15 minutes before removing from the tray. Eat straight away or cool down and place in the fridge where it will keep for 3 days. It is delcious eaten hot or cold.
