Overnight Breakfast/Brunch Casserole

READY IN: 45mins
Recipe by Melanie2590

This is different than your average breakfast casserole. It is so yummy and easy to put together. You can easily make this into a light dish by substituting egg beaters and light cheese. I've made it both ways and both are equally good! Also, if you cut the recipe in half, use 2 whole eggs and 1 egg white. If you're a vegetarian, this is also good without bacon!

Very flavorful and delicious - a great spinach and mushroom flavor combo.
