- Preheat the oven to 350°F. Grease a 9x13 pan with spray or a little softened butter. 
- Without separating the rolls, cut them in half horizontally with a serrated knife. Place the bottom half of the rolls in a 9x13-inch baking dish. - 12 count package King's Hawaiian Rolls 
- Spread 2 tbsp. mustard on the bottom half of the rolls. - 1/4 cup Dijon or yellow mustard, divided 
- Add the ham in an even layer, folding and overlapping slices as needed. - 8 oz. thinly sliced deli ham (I like a honey ham or black forest ham) 
- Arrange a layer of cheese on top.  - 7 oz. thinly sliced Swiss cheese, about 12 slices 
- Add the pulled pork on top. - 1 lb. pulled pork* 
- Then add the pickles.  - 3-4 dill pickles, thinly sliced lengthwise 
- Spread the last of the mustard on the top half of the rolls and place on top.  
- Melt the butter in the microwave (cover with a paper towel so it doesn't splatter) and stir in the parsley, salt and garlic powder. Brush/pour butter mixture on top of the rolls and cover with foil. Bake until heated through and the cheese is melty, about 20-25 minutes. Uncover and bake for about 5-10 more minutes until the tops are golden brown and rolls are heated through. You can brush a little more melted butter to add on top when they come out of the oven to give them a glistened look. - 1/4 cup unsalted butter, melted, 1 Tbsp. fresh parsley, finely chopped, 1/2 tsp. kosher salt, 1/2 tsp. garlic powder 
- Whisk together ingredients for the aioli. - 3/4 cup mayonnaise, 1/4 cup Dijon, 4 cloves garlic, pressed with a garlic press or finely minced, 1/2 lemon, ~2 tsp., 1/4 tsp. ground cumin, salt and pepper, to taste 
- Slice and serve warm with aioli sauce on side for dipping if desired.
