Ingredients:
1 medium onions
1 lb sliced ham
3/4 lb swiss cheese
1 cup butter or 1 cup margarine, at room temperature
3 tablespoons poppy seeds
1 teaspoon Worcestershire sauce
3 tablespoons prepared mustard
3 (8 ounce) packages party rolls
Directions:
Preheat the oven to 325 degrees.
Using a food processor, in separate batches chop the onion, ham and cheese.
In a medium-size bowl combine the butter, poppy seeds, Worcestershire and mustard and add the onion, ham and cheese.
Split the pans of rolls in half horizontally, leaving the sheet of bottom halves in the pan. Spread each bottom with 1/3 of the ham and cheese mixture.
Top with the sheets of top halves and cut into individual servings by following the outline of the rolls. The rolls can be frozen at this time.
At serving time, cover the foil pans with aluminum foil and heat through, 25 to 30 minutes (less if not frozen).
