Squash Casserole

about 4 lbs yellow and zucchini squash sliced thinly
1 green and 1 red bell pepper sliced into thin strips
1 large Spanish or vidalia onion sliced thinly
1 lb fresh ground hot pork sausage
1 1/2 cup homemade or canned stewed tomatoes
1/2 lb Monterey jack and mozzarella cheese, grated

Chop the tomatoes into medium chunks. Fry the sausage, breaking it into chunks as it cooks, until it is no longer pink. Drain off grease. Spray a deep baking dish with cooking spray. Layer the squash over the bottom of the dish. Follow with layers of onion and sausage. Continue layering until all layer ingredients are used up. Pour tomatoes over top and sprinkle with cheese. Bake at 325 F for 30 to 45 minutes or until the squash is tender. (time varies according to the shape of the dish)
