Easy Make Ahead Breakfast Casserole

"When I have to feed a crowd breakfast I whip up this simple, but satisfying Sausage and Spinach Strata. It’s one of my favorite Make Ahead Breakfast Casserole recipes because it’s so easy and always gets rave reviews. It’s also very filling so you can feed a crowd without breaking the bank and without spending all morning standing over a hot stove. In fact, since this is a make ahead breakfast casserole, you do all the work the night before (and it’s not much work). In the morning, you can pop it in the oven while you get coffee started."
