Melt butter and flour to make a smooth paste. Add milk and broth, then all ingredients. Cook over medium heat, stirring constantly. When it begins to thicken, place in a baking dish. Top with cheese and bake. This may be poured over cooked rice instead of being used as a casserole dish. Bake at 300 degrees for 45 minutes.
