Crustless low fat quiche

I really love quiche. It's so hearty and is endlessly adaptable but unfortunately it's not great for a slimmer's waistline! We recently tried out this recipe which is based around Slimming World and their rules for food. I tend to eyeball the ingredients based around the size of the dish I'm using but the basic recipe is as follows:

Ingredients:
3 eggs
1 tub of cottage cheese
1 onion
1 clove of garlic (crushed)
A little cheddar (grated)
Fillings of your choice - mushrooms, courgettes, spinach, sausages (I've used veggie ones before too), basically anything that goes in a quiche...

Method:
In a frying pan, fry the onion, garlic and other fillings that need to be cooked.
In a large bowl, gently beat the eggs and add the cottage cheese, season with salt and pepper.
Add the ingredients from the pan into the egg misture and mix well. Pour into a baking dish (I use a ceramic casserole dish). Sprinkle the cheddar over the top and place in the oven at 180-200C until set (around 25 minutes depending on the size of the dish).
