Step 2: While the oven is preheating, slice the rolls in half horizontally to separate the top and bottom of the rolls. Put the bottom half inside of a baking dish.
Step 3: Completely cover the bottom buns with Swiss cheese, then top the Swiss with an even layer of ham.
Step 4: On top of the ham, cover with dill pickle slices and then a layer of shredded gruyere cheese.
Step 5: Place the top layer of buns on the sliders and put them into the preheated oven or grill for five minutes.
Step 6: While the sliders are in the oven, melt the butter and whisk in all of the ingredients for the dijon butter sauce.
Step 7: After five minutes, remove the sliders and glaze the top with a light coat of the dijon butter sauce. Set the rest of the sauce aside, keeping it warm, and return the sliders to the oven or grill for an additional 15 minutes or until the buns are golden brown and the cheese has melted.
Step 8: Remove the sliders, cut into individual servings and serve with remaining warm dijon butter dipping sauce. I also love to pair these with homemade pickled red onions or pickled jalapeños.
