Creating Ham and Cheese Sliders on Hawaiian Rolls is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Baking Dish: Grease a baking dish or line it with parchment paper.
3. Slice the Rolls: Carefully slice the Hawaiian rolls in half, without separating them.
4. Layer Ham and Cheese: Place half of the slices in the dish, layer with ham and then cheese, and finally place the remaining rolls on top.
5. Make the Butter Mixture: In a bowl, combine melted butter, Dijon mustard, poppy seeds, brown sugar, and a pinch of salt and pepper.
6. Brush the Mixture: Pour the butter mixture evenly over the rolls, ensuring every section is well-coated.
7. Cover with Foil: Cover the baking dish with aluminum foil and bake for 15-20 minutes.
8. Uncover and Bake: Remove the foil and continue baking for an additional 5-10 minutes, or until golden and bubbly.
9. Serve Warm: Remove the sliders from the oven and allow them to cool slightly before serving.

These straightforward steps will not only guide you through the process but also ensure that your sliders emerge perfectly cheesy and flavorful!
