Preheat oven to 350 degrees F. Spray an 11-inch rectangular baking dish with nonstick cooking spray.
Using a large serrated knife, slice the rolls in half so you have a “slab” of tops and a “slab” of bottoms; don't pull the rolls apart and slice individually because you want to keep them connected. Hold the top with one hand to keep them steady.
Layer the sliders as follows: Provolone slices, sliced ham, Mozzarella cheese.
Replace the top half of the rolls over the cheese.
In a small bowl, combine melted butter, Worcestershire sauce, garlic, fresh parsley and a pinch of salt and pepper. Pour or brush the mixture onto the tops of the rolls.
Cover loosely with nonstick foil (careful not to let it touch the tops of the bread to avoid sticking - use toothpicks if necessary to "lift" the foil).
Bake in a preheated 350 degree oven for 15 minutes. Remove foil and continue to bake for another 10 minutes or until tops are nice and golden brown.
Let cool and cut
