Heat coals or gas grill for direct heat. Cut six 18x10-inch pieces of heavy-duty aluminum foil. Spray with cooking spray. Mix beef, soup mix (dry), egg, milk and bread crumbs. Shape into 6 loaves, 4x2 1/2x1 inch. Place loaf on one side of each foil piece; top each with about 1 tablespoon of the ketchup. Place about 1/2 cup potatoes and 1/2 cup carrots around each loaf.
