Creating Ham and Cheese Sliders on Hawaiian Rolls is a breeze if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Baking Dish: Lightly grease a 9×13-inch baking dish.
3. Assemble the Rolls: Keep the Hawaiian rolls connected and slice them in half horizontally. Place the bottom half in the prepared baking dish.
4. Layer the Ham: Evenly layer the sliced ham on the bottom half of the rolls.
5. Add the Cheese: Place the Swiss cheese slices over the ham layer.
6. Top with Roll Lids: Place the top halves of the Hawaiian rolls back on top of the cheese.
7. Make the Butter Mixture: In a bowl, combine melted butter, Dijon mustard, brown sugar, garlic powder, and onion powder. Whisk together until well blended.
8. Brush the Butter Mixture: Generously brush the butter mixture over the top of the rolls. If using poppy seeds, sprinkle them generously over the buttered tops.
9. Cover with Foil: Cover the baking dish loosely with aluminum foil.
10. Bake: Place the dish in the preheated oven and bake for 15 minutes.
11. Remove the Foil: After 15 minutes, remove the foil and bake for an additional 10 minutes, or until the sliders are golden brown and the cheese is melted.
12. Serve Hot: Remove from the oven and let cool slightly before slicing into individual sliders.

Follow these steps, and you’ll be rewarded with deliciously cheesy Ham and Cheese Sliders that everyone will love.
