An easy and delicious way to make hot sandwiches for a crowd.

  • Servings: 12
  • Prep Time: 15 mins + 3 hrs
  • Cook Time: 25 mins
  • Total Time: 3 hrs 40 mins


1× 24 Count Pack Kings Hawaiian Rolls, party potato rolls work fine too
½ lb Shaved Ham
12 slices Swiss Cheese
1 stick Salted Butter
1 tsp Dijon Mustard
1 tsp Worcestershire Sauce
1 tsp Dried Onion
1 tsp Poppy Seeds


Slice the King’s Hawaiian rolls in half. Line the bottom of a 9X11" baking pan with the bottom halves of the rolls (they should just fit).

Spread the ham over the rolls, and then layer the Swiss cheese on top. Place the other halves of the rolls on top. Set aside.

In a small sauce pan, combine the butter, mustard, Worcestershire sauce, and dried onions. Over medium heat, stir until the butter has melted to create the sauce. Pour the sauce over top of the rolls, and then sprinkle the tops with the poppy seeds. Cover the pans tightly with aluminum foil, and then refrigerate for at least three hours – or overnight (better).

When You’re Ready to Bake:

Preheat the oven to 350°F. Place the covered baking pan in the oven for 20 minutes. Uncover and bake for an additional 5 minutes, or until the cheese has finished melting.

Serve warm or at room temperature. Makes 24 mini-sandwiches.
