Serve the flavors of a traditional Cuban sandwich on fluffy slider rolls for a quick meal, a party or on game day. Savory roast pork, ham and melted Swiss cheese are complemented by tart yellow mustard and slices of dill pickle.
Combine mayonnaise and mustard in a small bowl and set aside.
Cut the entire pack of rolls in half horizontally (keeping all tops connected and all bottoms connected). Transfer rolls to a 9x13-inch baking dish brushed with 1 tablespoon of the melted butter.
Spread the mayonnaise mixture evenly over bottom rolls.
Place roast pork and ham on bottom rolls. Top with the Swiss cheese, pickles and the top rolls.
Drizzle the remaining 7 tablespoons melted butter over the top rolls. Wrap in aluminum foil and refrigerate overnight. (If desired, place a baking sheet and a weight on top to press the sandwiches, similar to the traditional pressed Cuban sandwich.)
Preheat oven to 350℉. Remove top baking sheet and weight (if using) and bake for 15 minutes. Remove the aluminum foil and continue to bake uncovered for 5 minutes longer or until golden brown and warmed through.
