1-First, preheat your oven to 350°F (175°C). Carefully slice the package of Hawaiian rolls in half horizontally, keeping the top and bottom halves intact but separated. This sets the base for your sliders and makes layering easy. Place the bottom half in a baking dish to hold everything together.

2-Second, layer the sliced deli ham evenly over the bottom half of the rolls. For a dietary adaptation, use your chosen protein substitute such as marinated tofu or turkey slices. This step adds the savory element that contrasts with the sweet rolls. Make sure to fold the ham if needed for even distribution.

3-Third, place Swiss cheese slices evenly over the ham layer, or use a vegan cheese option if preferred. This creates the gooey center that melts perfectly during baking. Fourth, replace the top half of the rolls onto the cheese for a neat sandwich structure.

5-Fifth, in a small bowl, mix melted butter, Dijon mustard, Worcestershire sauce, onion powder, and kosher salt until combined. Evenly brush this butter mixture over the top of the rolls, ensuring full coverage. Sixth, sprinkle with poppy seeds for a nice crunch and added flavor.

7-Seventh, cover the assembled sliders tightly with aluminum foil and bake in the preheated oven for 20 minutes. This helps the cheese melt without drying out the bread. Remove the foil and bake for an additional 7 to 8 minutes until the rolls are lightly browned and the cheese is fully melted. Finally, let the sliders cool for a few minutes before transferring to a cutting board, slicing individually, and serving.
