What You Need:
1 package (15 oz each) 24 ct party rolls (Martin’s Potato Rolls)
12 ounces thin sliced ham (Hillshire Farm Ultra Thin Honey Ham)
6 slices Swiss cheese
1 stick butter
2 tablespoons yellow mustard
1 teaspoon Worcestershire sauce
1 ½ tablespoons dried minced onion
2 tablespoons poppy seed
What You Do:
Cut rolls in half and lay them in a casserole dish. Each roll receives one piece of folded ham (or tear two folded slices of ham in half and place each half on two rolls). Add ¼ of a slice of cheese to rolls and top with roll. Melt butter; add mustard, poppy seed, onion, and Worcestershire sauce. Spread mixture over rolls. Wrap casserole dish in foil. Bake at 375 ° for about 15 minutes, or until thoroughly heated and cheese is melted.
Side note:after making this, there was WAY too much "sauce" for the top of the sandwiches, the topping part could probably be cut in 1/2.
