Making Ham and Cheese Sliders on Hawaiian Rolls is a straightforward process. Follow these simple steps for guaranteed success:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Rolls: Slice the pack of Hawaiian rolls in half horizontally, keeping them attached.
3. Arrange Ham and Cheese: Lay 6 slices of ham evenly across the bottom half of the rolls. Follow with 6 slices of cheese.
4. Top with Remaining Ham and Cheese: Place the remaining ham and then cheese on top.
5. Prepare Butter Mixture: In a small bowl, mix the melted butter, Dijon mustard, garlic powder, and poppy seeds (if using).
6. Brush the Mixture: Pour this butter mixture over the tops of the sliders, making sure to coat them evenly.
7. Bake: Cover the sliders with foil and place them in the preheated oven. Bake for about 20 minutes, then remove the foil and bake for an additional 5-10 minutes until the cheese is melted and the tops are golden brown.
