Funeral Sandwiches

3/4 c. butter, melted
1-1/2 Tbsp. Dijon mustard
1-1/2 Tbsp. Worcestershire sauce
1-1/2 Tbsp. poppy seeds
1 Tbsp. dried minced onion
24 mini sandwich rolls (Hawaiian sweet rolls)
1 lb. thin deli ham
1 lb. thin Swiss cheese

In a bowl mix butter, mustard, Worcestershire sauce, poppy seeds and dried onion. Slice rolls and place bottoms in a buttered 9X13 baking dish. Layer half the ham on the rolls, followed by the cheese and the rest of the ham. Place the tops of the rolls onto the sandwiches. Pour the butter mixture over the rolls. Bake 350 degrees for about 20 minutes or until the rolls are lightly browned and the cheese has melted. Slice through ham and cheese to serve sandwiches.
