Place chicken pieces in a lightly greased 9x13 inch baking dish. In a large bowl combine the cranberry sauce, salad dressing and soup mix and mix well. Coat chicken pieces with this mixture.
Cover dish and bake at 350 degrees F (175 degrees C) for 1 1/2 to 1 3/4 hours, or until chicken is cooked through and juices run clear.
Remove cover for the last 15 minutes of baking time.
