Follow these easy steps to create your Ham and Cheese Sliders on Hawaiian Rolls:

1. Preheat your oven to 350°F (175°C).
2. Prepare the baking pan: Grease a 9×13-inch baking dish to prevent sticking.
3. Slice the rolls: Carefully cut the Hawaiian rolls in half, keeping them attached.
4. Layer the ham: Place slices of ham on the bottom half of the rolls in the baking dish.
5. Add cheese: Layer slices of cheese on top of the ham.
6. Place the top half: Gently place the top half of the rolls over the cheese.
7. Prepare the sauce: In a bowl, mix melted butter, Dijon mustard, poppy seeds, garlic powder, and onion powder.
8. Brush the topping: Evenly brush the butter mixture over the top of the rolls.
9. Cover with foil: Cover the baking dish with aluminum foil to keep the sliders moist while baking.
10. Bake: Place the covered baking dish in the preheated oven and bake for 15 minutes.
11. Remove foil: After 15 minutes, remove the foil and bake for an additional 5-10 minutes, or until the tops are golden brown and the cheese has melted.
12. Serve warm: Carefully remove from the oven and let cool for a couple of minutes before slicing.

By following these steps, you will create an irresistible batch of ham and cheese sliders that are sure to delight everyone!
