Notes
***do not cook pasta all the way through or it will tear when stuffing. Leave it a little underdone, it will finish cooking when it bakes**or rotisserie or other cooked chicken*If you want a softer topping, combine stuffing mix with a little melted butter and water before putting on casserole
