In a bowl, mix together the melted butter, brown sugar, Dijon mustard, Worcestershire sauce, poppy seeds, and dried minced onion until well combined.

Cut the rolls in half horizontally (keeping them all connected as one piece if possible). Place the bottom half in the prepared baking dish. Layer half of the ham on the bottom buns, then add all of the cheese slices, then top with the remaining ham. Place the top halves of the rolls over everything.

Pour the butter mixture evenly over the top of the rolls. Cover the dish tightly with foil and bake for 15 minutes.

Remove from the oven and take off the foil. Put the sliders back in the oven uncovered and bake for another 10 minutes until the tops are golden brown.

Take the sliders out of the oven, cut them apart, and serve immediately while they're hot and the cheese is melted!
