• 1 12-count package Hawaiian sweet rolls
• 3/4 lb cooked deli ham, thinly sliced
• 3/4 lb Swiss cheese, thinly sliced
• 1/2 cup unsalted butter, melted
• 1 Tablespoon Dijon mustard
• 1 Tablespoon poppy seeds
• 2 teaspoons dried minced onion
• 2 teaspoons Worcestershire sauce
• 1/4 teaspoon salt
• 1/4 teaspoon pepper

Preheat oven to 350F. Line a baking sheet with parchment paper and set aside. Without separating the rolls, use a large serrated knife to slice the slab of rolls in half. Place the bottom section of rolls on the prepared baking sheet. Evenly layer the ham over the rolls, followed by a layer of cheese. Add the top section of rolls.

In a medium microwave-safe bowl, add the butter, mustard, poppy seeds, onion, Worcestershire sauce, salt, pepper, and whisk to combine. Slowly pour the butter mixture over the rolls and use a spatula to spread the mixture evenly over the tops. Cover with aluminum foil and bake covered for about 20 minutes or until cheese has melted.

Uncover and cook for an additional 3-5 minutes, watching to make sure they don’t burn. Slice into individual sandwiches and serve immediately.
