Preheat the oven to 350 Fahrenheit
Brush the bottom of the baking pan with a little butter.
Slice the Hawaiian rolls in half crosswise keeping the bunch together in one large top and bottom piece.
Spread mustard on the cut side of the bottom buns.
Place ham on the buns overlapping to cover completely - layer 7 or 8 slices as you prefer.
Place cheese on top of ham - layer 5-6 slices.
Add a layer of the mojo pork evenly on top of the cheese.
Add the pickles on top of the pork - if using slices use about 6 for chips use about 12 - just make sure that when cut each slider has some pickle.
Add another layer of cheese.
Add more mustard to the cut side of the top bun - if you like.
Place the top on and brush with more melted butter. Sprinkle with a little kosher salt.
Cover the pan with aluminum foil and bake for 20-30 minutes to warm through and melt the cheese.
Remove the foil and bake for an additional 5-8 minutes to brown and crisp the top.
Allow the sliders to cool for a few minutes then remove from the pan and cut into 12 pieces.
