There is so much to love about a breakfast casserole! Plus, breakfast is often the hardest meal to consume at least 20 grams of protein. -- Bake it once, and eat it all week long! -- Portions large enough to feed your entire family. -- Easy meal prep – leftovers can even be frozen for a quick and easy breakfast on busy mornings. -- Adds some variety to your typical breakfast and often easier than making eggs, bacon, potatoes, etc. separately.
