<human>:  How do I make a quiche?
<bot>: To make a quiche, start by preheating your oven to 350 degrees Fahrenheit. Grease a 9-inch pie dish. In a bowl, mix together 4 eggs, 1/2 cup of milk, 1/4 teaspoon of salt, and 1/4 teaspoon of pepper. Take one 9-inch unbaked pie crust and place it in the greased dish. Pour the egg mixture in the crust and add 1 cup of any filling ingredients, such as cheese, bacon, or spinach. Bake for 30 to 35 minutes, until the center is set and a knife inserted in the center comes out clean. Let cool before serving.
