Preparation

• 1
  Preheat the oven to 200 degrees, 180 degrees fan oven.
• 2
  Lightly grease a deep baking tin, about 22cm square, with a little softened butter.
• 3
  Line the baking tin with the ready rolled pastry, leaving a pastry rim of about 4cm around the edge.
• 4
  Peel and thinly slice the onion. Thinly slice the courgette. Deseed, halve and cut the peppers into strips. Halve the cherry tomatoes.
• 5
  Heat a tablespoon of oil in a frying pan and gently sauté the sliced onion for 2-3 minutes. Stir in the pepper strips and cook over a low heat for another 3 minutes. Tip into a bowl and leave to one side.
• 6
  Heat another tablespoon of oil in the same pan to a medium heat and briefly cook the courgette slices on both sides, so that they are just brown. Leave them on a plate covered in kitchen towel. You may need to do this in 2 batches.
• 7
  In a large bowl, beat the eggs. Add the cottage cheese, season with salt and black pepper and mix together. Stir in the cooked red onion and peppers. Snip in the chives and mix well together.
• 8
  Spoon the mixture evenly into the pastry case then arrange the courgette slices and the tomato halves on top.
• 9
  Grate the cheddar cheese and scatter it all over the top of the flan. Bake in the preheated oven for about 30 minutes, or until the flan is cooked through and the cheese is bubbling and golden brown.
