Preheat the oven to 170 degrees C (fan).
Place a medium pan on a medium heat and spray with a low calorie cooking spray.
Add the chopped leek, all peppers and fry, mixing frequently, for about 5 minutes. In the end of cooking it, add the asparagus.
Take a medium baking dish (I use a small one and I had the batter left for one ramekin as well) and spray it with oil spray, to prevent from future sticking. Place the veg mix in the dish.
In a medium bowl, beat the eggs with a whisk, then add the cottage cheese and season. Whisk again. Pour the egg mixture on the vegetables in the dish and mix a bit.
Bake for 15 - 20 minutes, until the eggs are cooked.
If you have, you can sprinkle it with some fresh parsley.
