3 tablespoons yellow mustard
1 tablespoon mayonnaise
12 dinner roll-sized potato buns (like Martin's), sliced in half
12 slices deli ham (about 1/2 pound)
1/2 pound sliced roasted pork shoulder, or un-sauced pulled pork
24 round dill pickle slices
12 slices deli Swiss cheese (about 1/2 pound)
Vegetable oil for brushing the rolls
Preheat the oven to 400°F. Line a 9x13-inch rimmed baking sheet with parchment paper.
Stir the mustard and mayonnaise together in a bowl, then open each roll and spread the mustard mixture on both sides.
Line the rolls up on the prepared baking sheet and fill each one with ham, roast pork, pickles, and cheese. Fold the slices of meat and cheese over on each other a few times as needed to make them fit loosely within the bounds of each roll.
Close each roll and lightly brush the tops with vegetable oil.
Place a second sheet of parchment paper on the sliders, then top with a large, heavy baking sheet or a double-burner griddle so that the sandwiches are pressed down.
Place in the oven and bake for 10 minutes, until the cheese is completely melted and the sandwiches are toasty. Serve warm or at room temperature.
Recipe Notes
- Make and take:The sandwiches can be assembled up to 4 hours in advance. Cover the sheet pan with plastic wrap and refrigerate until ready to bake on site. Or press and bake the sandwiches, then reheat in a 300°F oven if desired.
