Preheat oven to 180ºC . Beat the eggs. Brush pie shell with beaten egg and pre-bake for 5 minutes. Allow to cool for a couple of minutes. Combine cheese and filling material and place in pie shell. Dust with salt, pepper and herbs. Combine half & half and eggs and pour over all. Leave a little room for expansion. Bake 30-40 minutes (golden brown and a knife inserted in the center comes out clean). Allow to rest for about 10 minutes before serving. It is a good idea to place your pie pans on a cookie sheet just in case this boils over. Re: measurements. Since you generally buy a dozen eggs, frozen pie shells come two to a pack, half and half is sold in Pints and it is easy to buy a big enough brick of cheese, I usually double this and make two quiches. They freeze well and make great leftovers and are a wonderful breakfast. Re: fillings ... anything you want. Suggest spinach, chopped brocoli, onion, green pepper, crab, shrimp, sausage, bacon, ham, turkey, etc.
