Sweet Ham and Swiss Sliders

Sweet Ham and Swiss Sliders
12 dinner rolls, cut in half
24 slices Honey Ham
16 slices Swiss cheese
1/4 cup mayonnaise
1 1/2 tablespoons Dijon mustard
8 tablespoons butter, melted
1 teaspoon onion powder
1/2 teaspoon Worcestershire sauce
1 tablespoon poppy seeds
1/4 cup brown sugar
Preheat oven to 400°.  In a 9x13 glass baking dish, place bottom half of dinner rolls and top with 2 slices of ham and 1 slice of Swiss cheese. Spread about 1 teaspoon of mayonnaise on each top-half of roll and place on top of ham and cheese. You want the rolls to be snug together.  In a small bowl combine the mustard, melted butter, onion powder, Worcestershire sauce, poppy seeds, and brown sugar. Mix until combined and evenly pour over the assembled rolls. You will not need all the sauce. Cover with foil and refrigerate for up to 20 minutes.  Bake covered with foil for 10 minutes, remove the foil and bake for an additional 5-10 minutes or until the tops are browned, and cheese is melted. Serve hot or warm.
