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

1. Preheat your oven to 350°F (175°C).
2. Prepare the Baking Dish: Grease a 9×13 inch baking dish with cooking spray or butter.
3. Assemble the Base: Without separating the rolls, slice the entire pack of Hawaiian rolls in half horizontally.
4. Place the Bottom Half: Place the bottom half of the rolls in the greased baking dish.
5. Layer the Ham: Evenly distribute the sliced ham over the bottom half of the rolls.
6. Add Cheese: Layer the sliced Swiss cheese over the ham for that melty goodness.
7. Replace the Top Half: Place the top half of the rolls back onto the assembled bottom half.
8. Prepare the Sauce: In a bowl, mix together the melted butter, Dijon mustard, Worcestershire sauce, onion powder, poppy seeds, salt, and pepper.
9. Brush the Sauce: Generously brush the prepared sauce over the tops of the Hawaiian rolls.
10. Bake: Cover the dish with aluminum foil and bake for 15 minutes. Then, remove the foil and bake for an additional 5-10 minutes, or until the tops are golden brown.
11. Cool and Slice: Once done, let the sliders cool for a couple of minutes before slicing into individual portions.
12. Serve: Transfer to a serving platter and enjoy with your favorite sides.
