This low-carb bacon, egg, and spinach breakfast casserole has rescued my mundane breakfast! For several months now, I have been eating the same breakfast every day. Peanut butter toast on whole wheat bread, topped with honey is my favorite quick and easy breakfast. I love it, but I need to switch it up! I also wanted to cut back on carbs this week!

This casserole is easy to make. The key word here is LAYERS. Create the first layer by adding sauteed veggies to the bottom a baking dish.

I love casseroles! I really should make them more often. I love to combine a bunch of ingredients that pair well together, and then throw the dish in the oven and get back to life until it is finished baking. Casseroles are also a great way to sneak in nutritious veggies and high protein foods. A casserole will save you from having to prepare multiple side dishes for one meal.
