This crustless quiche has just enough eggs to be recognizably quiche-y, but most of the body comes from a surprising ingredient: pancake mix! One of the most popular brands we all know and love, Bisquick, actually started as a biscuit mix (hence the name) in the early 1930s. But as home cooks got creative with the product, the company started releasing cookbooks with dozens of recipes for cakes, breads and even donuts using the mix. This inventive hack for quiche was extremely popular in the ‘60s and ‘70s and, like all trends, has come back around as a quick, easy and reliable recipe. The filling here is a breakfast combo of bacon, onion and cheese, but feel free to customize it however you like.
