Making Ham and Cheese Sliders on Hawaiian Rolls is a simple yet rewarding process. Just follow these easy steps to enjoy delicious sliders:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare the Baking Dish: Lightly grease a baking dish with cooking spray or a little butter to prevent sticking.
3. Slice the Rolls: Carefully slice the Hawaiian rolls in half horizontally, keeping them intact as one piece.
4. Add the Ham: Layer the bottom half of the rolls with slices of ham, ensuring even coverage.
5. Add the Cheese: Place a slice of cheese on top of the ham layers to create a gooey filling.
6. Place the Top Rolls: Position the top half of the sliced rolls back on top of the cheese.
7. Mix the Topping: In a separate bowl, combine melted butter, Dijon mustard, garlic powder, poppy seeds, and brown sugar, if using. Stir until well combined.
8. Brush the Mixture: Pour the butter mix over the top of the roll layers, ensuring they are evenly coated.
9. Season: Sprinkle salt and pepper on top as desired for added flavor.
10. Bake: Cover the sliders with aluminum foil and bake for 15 minutes. Then, remove the foil and bake for an additional 10 minutes until the tops are golden brown.
11. Cut and Serve: Once baked, let them cool for a couple of minutes before cutting them into individual sliders.
