Brown ground beef, sausage, onions and oregano. Add tomato soup, cheddar cheese soup and water. Add noodles, place in large casserole or 9 x 13 inch pan. Bake at 350 degrees for 40 minutes. Top with slices of Velveeta cheese and bake until cheese melts. This is an easy recipe to double, use one casserole for now and freeze one for later.
