Beat butter, onion, poppy seeds, mustard, and Worchestershire
together in small bowl. Split rolls. Spread butter mixture on both
cut sides of rolls. Place one piece of ham and 1 slice cheese on
bottom half of each roll. Replace tops and place on cookie sheet.
Cover loosely with foil and bake 15 minutes or until cheese begins
to melt. These freeze very well.
