Preheat your oven to 180°C/160°C Fan/Gas 4.
Lightly spray 12 muffin cases with low calorie cooking spray or use silicon cases.
In a bowl, mix the cottage cheese, eggs, onion and salt & pepper with a fork until all mixed together well.
Spoon the mixture into the cases and top with the tomatoes, mushrooms and asparagus.
Bake in the oven for 25-30 minutes or until golden brown.
