Quiches are creamy, delicious pies that are easy to miniaturize but can still fill you up. Plus, they're a cinch to make. They're made primarily from eggs, which are one of the least expensive household staples. Of course, if you don't feel like whipping up a batch from scratch, the frozen varieties are also delicious.
Mini quiches can be made in miniature muffin tins. Standard ingredients for a good quiche include the aforementioned eggs, milk, cream, cheese (Gruyère is common, but can be substituted with Swiss or cheddar) and other variable ingredients, like spinach, onion, asparagus or chicken. Many easy recipes call for pieces of store-bought piecrust or crescent rolls to serve as the crust, although crushed saltine crackers held together with melted butter also works well. You can even opt to omit the crust altogether, if that's your personal preference.
