2. Prepare Baking Dish: Grease a 9×13-inch baking dish or line it with parchment paper for easier cleanup.
3. Slice Rolls: Carefully slice the slider rolls in half, keeping the tops attached to the bottoms.
4. Layer Ham: Place the bottom halves of the rolls in the prepared baking dish.
5. Add Cheese: Layer the sliced ham evenly over the rolls, followed by an equally generous layer of Havarti cheese.
6. Combine Toppings: In a small bowl, combine melted butter, Dijon mustard (if using), garlic powder, and parsley. Mix well.
7. Brush Mixture: Brush the prepared mixture generously over the tops of the rolls.
8. Cover with Top Halves: Place the top halves of the rolls back onto the slider bottoms.
