HOT COLBY HAM SANDWICHES

Steps:

• In a small bowl, combine the butter, mustard, onion, poppy seeds and sugar. Place roll bottoms, cut side up, in an ungreased 15 x 10 x 1 inch baking pan. Top each with colby cheese, ham and mozzarella cheese. Drizzle with half of the butter mixture.
• Replace roll tops. Drizzle with remaining butter mixture. Bake, uncovered, at 350 degrees for 10-15 minutes or until cheese is melted.
