Macaroni and cheese!! I cook a box of elbow macaroni as directed on the box and in a 9x13 inch lightly greased glass dish, I layer the macaroni and shredded cheddar. In between the layers, sprinkle with powdered mustard, salt, and pepper. Pour milk evenly around so that it comes about half-way up the side of the dish. Then bake for about 90 minutes in a 350 degree oven or until evenly browned. This was my DM's recipe for covered dish and it would always be gone in a flash!
