Freeze option: Bake meat loaves without topping. Cool meat loaves and freeze, covered, on a waxed paper-lined baking sheet until firm. Transfer meat loaves to resealable plastic freezer bags; return to freezer. To use, partially thaw in refrigerator overnight. Place meat loaves on a greased shallow baking pan. Prepare topping as directed; spread over tops. Bake in a preheated 350° oven until heated through.
