Preheat oven to 350 Degrees. Line a 9" x 13" baking pan with parchment paper, leaving an overhang on 2 sides.
Using a large serrated knife, slice the rolls in half so you have a slab of tops and a slab of bottoms; don't pull the rolls apart because you want them connected.
12 oz package of dinner rolls or Hawaiian rolls
Add 1/2 tsp. water to Spicy Beer Mustard to improve its spreading consistency.
2 Tb + 1 tsp Buzz Savories Spicy Beer Mustard
Place the bottom half of the rolls in the prepared pan, cut-side up, and spread 2 Tb of Spicy Beer Mustard on top. Add half the ham, layering it evenly over the bread, followed by all of the cheese. Add the remaining ham and finally, the top half of the rolls.
½ lb. thinly sliced Swiss cheese
In a small bowl, whisk together the butter, Worcestershire Sauce, dried onion, poppy seeds, salt and the remaining 1 tsp Spicy Beer Mustard. Brush the mixture all over the tops and sides of the bread and into crevices.
4 Tb unsalted butter, melted, 2 tsp dried minced onion, 2 tsp Worcestershire Sauce, 1 Tb poppy seeds, ¼ tsp salt
