Add the spinach, cherry tomatoes and spring onion to the tin. Combine the whisked egg, cottage cheese, salt and pepper in a bowl, then pour into the tin (gently bang the tin on a surface to allow the egg to spread). Top with the grated cheese and season well.
1 cup baby spinach, 0.5 cup cherry tomatoes, 2 spring onions, 4 eggs, 0.5 cup cottage cheese, sea salt & cracked black pepper, 0.5 cup mozzarella cheese
