Preheat oven to 325 degrees. Cut up chicken, onion, peppers and sausage. Boil pasta and drain (don't over cook). Mix pasta, sausage, onion, peppers, chicken and sauce. Put in a large deep dish. If it won't all fit, make a little side dish to freeze for lunch later. Top heavily with cheese. Bake at 325 degrees for about 45 minutes or until golden and bubbly.
