DIRECTIONS

In a large bowl, combine the first nine ingredients. Crumble beef over mixture and mix well. Pat into two ungreased 9-in. square baking pans.
    Bake at 350° for 15-20 minutes or until meat is no longer pink and a meat thermometer reads 160°; drain. Let stand for 10 minutes.
    Meanwhile, in a large saucepan, bring the water, milk, butter and salt to a boil. Stir in potato flakes. Remove from the heat.
    Invert one meat loaf onto a serving platter; invert the second loaf onto a cutting board. Spread 1-1/2 cups mashed potatoes over loaf on the platter. Carefully slide second loaf onto the potatoes.
    Spread 3-1/2 cups mashed potatoes over top and sides. Spoon remaining mashed potatoes into a pastry bag with open star tip #195. Pipe a shell border around bottom and top edges. Place ketchup and mustard in separate resealable plastic bags; cut a small hole in a corner of each bag. Pipe onto potato border. Yield: 8-10 servings.
