Step 1

Spray an 11-inch x 7-inch baking dish with nonstick cooking spray.

Step 2

In a small bowl, stir together the melted butter, mustard, honey, dried parsley, onion powder and garlic powder.

Step 3

Do not pull the rolls apart, simply use a large serrated knife to slice the rolls in half as you would slice a bagel, separating the tops from the bottoms. Place the layer of bottoms into the prepared baking pan, cut side up.

Step 4

Layer half of the ham onto the rolls. Next, layer the Swiss cheese over the ham, and top with remaining ham slices. Place the layer of tops onto the sandwiches.

Step 5

Brush all of the butter mixture evenly over the rolls. At this point you can cover and refrigerate for up to 4 hours, or bake immediately.

Step 6

When you’re ready to bake, preheat the oven to 350 degrees F. If your pan isn’t covered with foil, go ahead and cover it now.

Step 7

Bake covered sliders in the preheated oven for 12 minutes. Remove the foil from the baking pan, return the sliders to the oven and bake uncovered for an additional 10 minutes.
