• Preheat the oven to gas 4, 180°C, fan 160°C. Grease 6 holes of a muffin tin and put a disc of baking paper in the bottom of each.
  • Heat the olive oil in a small frying pan over a medium heat. Add the garlic, courgette and spinach. Cook for 4-5 minutes, stirring frequently to prevent the vegetables catching on the bottom of the pan. Remove from the heat and stir through the frozen peas.
  • In a large bowl, gently stir the cooked vegetables and cheese into the beaten egg. Divide the mixture evenly between the prepared muffin holes.
  • Bake for 18-20 minutes, until the fritattas are set and golden. Remove from the oven and leave to cool slightly, before releasing from the tin. Store in a plastic container
