Slice the entire package of Hawaiian rolls in half horizontally, keeping all the rolls connected. Place the bottom half on a cookie sheet.
Coat the inside of the rolls with dijon mustard.
Next, spread the cooked pulled pork evenly over the bottom half of the rolls.
Layer the Fillings
Place the ham slices on top of the pulled pork.
Top the cheese with pickles.
Finally, place the top half of the Hawaiian rolls on top.
Make the Glaze
In a small saucepan, melt the butter over low heat.
Once melted, remove from the heat and stir in the Dijon mustard, minced garlic, dried parsley, onion powder, garlic powder, and salt. Mix until well combined.
Glaze and Bake
Pour the glaze evenly over the top of the sliders. Use a pastry brush to make sure every roll is coated.
Cover the sliders with foil and bake for 15 minutes.
Remove the foil and continue to bake for another 5-10 minutes, or until the cheese is melted and the tops are golden brown.
Serve
Carefully remove the sliders from the oven.
Slice them along the original roll lines and serve warm.
