"Quiche is a great dish to make when you have small amounts of leftover meat, cheese or vegetables. My favorite combination is the classic trio of bacon, onion and Gruyere cheese, but spinach and mushrooms or roasted red peppers and onions make great vegetarian options. Just be sure that any vegetables you use are cooked and dried off -- uncooked vegetables leach liquid out into the custard, which ruins the quiche. The amount of filling is enough for a pie or tart pan 6 inches in diameter and 1 or 2 inches deep. I use a pan with a removable bottom to enable me to remove the quiche from the pan before slicing, but you can slice it in the pan as well. Use any crust recipe you like, but be sure to blind bake it or the bottom will become soggy...."
