This delicious breakfast recipe comes straight from my new book, The Gluten-Free Revolution! I love preparing these quiche cups on the weekend to have on hand for a quick breakfast option throughout the week. Can't deal with dairy? Try subbing the goat cheese for an extra helping of veggies, like mushrooms or bell peppers. (Note that the prep and cook times for the quiche cups assume that you have already prepared the caramelized onions ahead of time. See the accompanying recipe for how to caramelize an onion.)
