Low-Carb Crustless Quiche 

This recipe for low-carb crustless quiche is one I make about every other week. It’s quick and easy, and I can cut it in pieces and easily grab a bite from the fridge. I eat it cold and hot, and you can too. Low-carb crustless quiche is also a great quick snack.

The prep time on this recipe includes the time it takes to cook the crispy bacon. You can use already crumbled bacon to cut down on the prep time. This is a great recipe to make at the beginning of the week and keep in the fridge to enjoy for breakfasts or a snack.
