An egg bake is basically a frittata, a crustless quiche, a baked omelette if you will. Call it whatever you want. When you break it down, you really just throw whatever meat and veggies you like into a baking dish, pour some whisked eggs over it all, and bake it until it doesn’t jiggle. Oh, you can also add some cheese, if you’re into that kind of thing. But since I was shooting for a Whole30 recipe here, I left it out.
