Grate your cauliflower using a food processor or a hand grater so you have a mixture that looks like fine rice
Grate the mozzerella. Beat the eggs lightly and season with salt and pepper
Squeeze out any liquid in the cauliflower, then add in the grated mozzerella cheese and a third to half the egg
Mix with a fork or your hands to make a wet 'dough'
Grease your flan dish(es) then with your fingers press the 'dough into the dishes to make a 'shell'
Bake in a preheated oven at 200c for about 15 minutes till the shell is dry and light golden brown in colour
Add the quark to the egg and mix well.
Add your filling vegetables to the remaining egg. You could use any vegetables you like in a normal quiche; tomatoes, peppers, onions, mushrooms or a mixture. If you are using small quiche tins, like me, you may find it easier to lay the vegetables on the crust then pour the egg mixture over the top. Add the grated parmesan on top
Return to the oven and bake for a further 10-15 minutes till the filling is golden brown and puffed up. Serve hot or cold.
