1. Preheat the Oven:
- Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with aluminum foil or parchment paper for easy cleanup.
2. Prepare the Rolls:
- Slice the Hawaiian rolls in half horizontally as a whole sheet, keeping the rolls connected. Place the bottom half in the prepared baking dish.
- Spread mayonnaise on the bottom half of the rolls (optional).
3. Layer the Ham and Cheese:
- Layer the ham slices evenly over the rolls. Top with the Swiss cheese slices. Place the top half of the rolls back on top.
4. Make the Butter Glaze:
- In a small bowl, whisk together the melted butter, Dijon mustard, Worcestershire sauce, garlic powder, and poppy seeds.
5. Assemble the Sliders:
- Brush the butter glaze generously over the tops of the rolls, making sure to cover them completely.
6. Bake:
- Cover the baking dish with aluminum foil and bake for 15 minutes. Remove the foil and bake for an additional 10 minutes, or until the tops are golden brown and the cheese is melted.
7. Serve:
- Let the sliders cool for 5 minutes before slicing and serving.
