Zucchini Casserole

This recipe is very yummy and comes recommended by our family members!  I like to prepare this the night before, put it in the fridge overnight and then put it in the oven for dinner for a very easy and delicous hot meal!

½ large onion, halved and sliced very thin
1-2 medium zucchini or summer squash, sliced very thin
1 pound ground beef (or meat of choice)
12-16 oz tomato sauce or salsa
1-1 ½ cups grated cheese
Salt and pepper to taste

In the casserole layer some tomato sauce, onion, zucchini, beef, tomato sauce, and cheese.  Repeat another round of the same layer topping off with a good layer of cheese.  Season with salt and pepper, bake in 350 degree oven for 1.25-1.5 hours, and serve.
