Using a serrated knife, slice the entire slab of rolls horizontally without separating them. Place the bottom half into the baking dish.

Arrange an even layer of ham over the rolls, followed by cheese. Distribute evenly so every slider gets the same balance.

Place the top half of the rolls back on, pressing gently.

In a small saucepan or bowl, melt butter and stir in brown sugar, mustard, Worcestershire sauce, garlic, and pepper. Heat just until combined and smooth.

Pour or brush the glaze evenly over the tops of the rolls, letting it drip down the sides and into the seams.

Cover loosely with foil and bake until the cheese melts and the sliders are heated through.

Remove the foil and bake briefly until the tops are lightly golden and glossy.

Let the sliders rest for a few minutes, then cut along the seams and serve warm.
