This makes two 9" quiches, which sounds like a lot, but it keeps really well. Since it takes a full package of most of the ingredients for two, it's easier to just make two.
1 twin-pack deep-dish pastry pie crusts
2 cups (one pint) half-and-half
1 cup chopped ham (I usually use the Hormel canned ham, one can is perfect. It's where the tuna is in most supermarkets.)
1 cup grated cheese (cheddar, or casserole blend)
1 cup chopped onion (or less, to taste. You can also use onion powder if you don't have onions on hand. I recommend the prechopped frozen onions, cause I'm lazy.)
salt-and-pepper to taste.
1) Take crusts out of freezer and wrappings. Leave on countertop to thaw a bit.
2) Preheat oven to 400 degrees.
3) Prick pie crust bottoms with fork all over, bake 5 minutes, pull back out. (this way the crusts aren't soggy.)
4) In large bowl, lightly beat 4 eggs. Beat in half-and-half, salt and pepper. Sit aside.
5) Sprinkle half of onions, ham, and cheese into each crust.
6) Pour half of egg mixture into each crust.
7) Bake at 400 degrees for around 35-40 minutes, or until egg filling is set and golden brown on top.
Enjoy! It keeps really well, just cover in foil and put in fridge after it cools. It's also a great thing to take to potlucks and family things, as it's easy to make in advance and it looks so much more complicated than it is. The crusts tend to burn a bit around the edges, if that worries you put a rim of tinfoil over the edges when you put them in to bake.
You can experiment with the fillings. I've used ham, broccoli and white cheeses; ground beef, cheddar, and bacon for a bacon-cheeseburger effect; and taco beef, green peppers and cheddar for a Mexican taste.
