Preheat your oven to 350°F (175°C).

Slice the slider rolls in half horizontally, keeping the top and bottom halves intact. Place the bottom halves in a greased 9x13-inch baking dish.

Layer the ham evenly over the bottom halves of the rolls, followed by the Swiss cheese slices. Place the top halves of the rolls on top to create sandwiches.

In a small bowl, whisk together the melted butter, Dijon mustard, minced garlic, Worcestershire sauce, dried parsley, onion powder, and salt.

Using a pastry brush or spoon, evenly pour the garlic butter mixture over the top of the sliders, ensuring the tops are well coated.

Cover the baking dish with aluminum foil and bake in the preheated oven for 15 minutes.

Remove the foil and bake for an additional 5 minutes or until the tops are golden brown and the cheese is melted.

Remove from the oven and let cool for a few minutes. Serve warm and enjoy!
