Preheat the oven to 350°F.
In a small bowl, combine melted butter with Dijon mustard, honey, Worcestershire Sauce, poppy seeds, and dried minced onion. Whisk to combine.
Slice the tops off the whole sheet of rolls and carefully set them aside until ready to use. Lay the bottom halves of the rolls in a 13×9 casserole dish.
Spread a thin layer of mayonnaise on rolls, then layer on cheese and ham slices.
Carefully place the bun lids on top and pour the butter-mustard glaze over top.
Bake in the oven preheated to 350°F for 15-20 minutes until the cheese is nicely melted and the sliders are warmed through. Serve and enjoy!
