This quiche makes an incredible breakfast or afternoon snack, and offers you the ability to use almost any vegetable combination you'd like. It's also a great way to use all of those random bits of cheese you may have collected in your fridge. Make sure to use grass-fed and organic dairy products when at all possible. If you want to skip the yogurt just replace it with two more eggs. Although perfectly delicious without meat, clients also love just a little Maine bacon, sausage or ham added to the filling.
