Preheat your oven to 350°F (175°C).

Without separating the rolls, slice the Hawaiian sweet rolls horizontally to create a top and bottom layer. Place the bottom layer in a 9x13-inch baking dish.

Layer the slices of ham evenly over the bottom layer of rolls, followed by the slices of Swiss cheese.

Place the top layer of rolls over the ham and cheese to form sliders.

In a small bowl, whisk together the melted butter, Dijon mustard, Worcestershire sauce, garlic powder, poppy seeds, salt, and black pepper.

Evenly brush the butter mixture over the tops of the sliders, making sure to cover each roll completely.

Cover the baking dish with aluminum foil and bake in the preheated oven for 15 minutes.

Remove the foil and bake for an additional 5-7 minutes, or until the tops of the rolls are golden brown and slightly crispy.

Remove the sliders from the oven and let them cool slightly before serving. Use a sharp knife to cut them into individual sliders.
