This is an excellent casserole to make the night before, or for an easy dinner night. It is quick and easy to assemble. It’s like a big ole omelet. Just layer all the ingredients in the casserole dish and cover with foil and refrigerate. Next morning, remove foil and pop it in the oven. It also keeps for 2-3 days in the frig after it is cooked. Serve it up with a plate of sausage links, bacon, toast and fruit. You can also change the main ingredients to anything you like....cooked crumbled sausage, Canadian bacon, mushrooms, more cheese. All delicious!
