Preheat oven to 425 degrees. Spay pizza pan with a non-stick spray. Roll out pizza dough in pan. Ladle gravy over pizza dough, sprinkle onions over the gravy. Add stuffing, chopped turkey, and top with cheese to the pizza. Bake pizza for approximately 15 - 17 minutes or until cheese is golden brown. When pizza is removed from oven add the jelled cranberry sauce in small portions over the pizza.
