<human>:  How do I make a basic quiche?
<bot>: First, preheat your oven to 375°F. Next, prepare a 9-inch deep-dish pie crust and place it in a 9-inch pie plate. In a bowl, mix together 3 eggs, 1 cup of half-and-half or light cream, 1/2 teaspoon of salt and some freshly ground pepper. Pour the egg mixture into the crust and add 2 cups of your favorite cheese, such as Swiss, cheddar, Gruyere, or a combination. Then, if desired, add desired vegetables such as spinach, mushrooms, or onions. Bake for 40 minutes or until the top is golden and a knife inserted into the center comes out clean. Enjoy your homemade quiche!
