24 slices Ham
24 slices Swiss cheese
1 cube butter, melted
¼ cup brown sugar
2 Tbsp. Dijon mustard
1 Tbsp. Worcestershire sauce

Make sandwiches with rolls, ham and cheese. Place on jellyroll pan with edges all touching.
Mix together the rest of ingredients and brush tops of sandwiches liberally with sauce, then pour remaining sauce over all. Cover pan with foil and refrigerate for 4 to 24 hours. Preheat oven to 350 degrees. Bake rolls, covered, for 10 minutes, then remove foil and bake another 10 to 15 minutes until the tops are golden brown.
