3Add cream cheese and stir until totally mixed. At this point you may want to add more milk, but do it sparingly.
4In a large bowl, mix all ingredients, (tuna, noodles, sauce, and seasonings). Pour into a greased casserole pan and top with flavored breadcrumbs, crushed crackers, or French fried onion rings and bake in a 350 degree oven for 45-55 minutes.
