In a large bowl, mix together all the ingredients except for the sauce.
Line a 9 x 13 baking dish with aluminum foil, and spray with nonstick.
Form a loaf with the mixture in the pan, then pour tomato sauce over it, covering the whole loaf.
Cover with aluminum foil, and put in the oven for 1 hour and 45 minutes - 2 hours.
Remove foil, and let cook for an additional 15 minutes in oven.
Once out of oven, remove meatloaf from pan and put on a serving dish.
