Quiche packs the appeal of an omelet without the fuss, making it easy to serve a home-cooked breakfast for a crowd. This simple sausage and cheddar quiche tastes fantastic as is, but the recipe also allows for customization with other favorite ingredients. Use a regular or gluten-free frozen pie crust or ready-made pastry, or follow the instructions for homemade crust. You might end up with extra filling if you use a frozen crust. No need to waste it; just bake it without a crust in a small buttered baking dish or ramekin.
