Step 1

Prepare the butter sauce in a small bowl - melt the butter, add the spices and seasoning. Add about a third of the sauce to the bottom of a baking pan.

Step 2

Slice the slider buns in half. Slather mustard on both sides of the sliced buns. Place the bottom halves of the bun in the buttered baking dish.

Step 3

Top the bottom half of each bun with 1/2 slice of cheddar, 2 pieces of thinly sliced deli ham, sliced pickles and top with layers of Swiss cheese. Finish by adding the top of the bun.

Step 4

Brush the remainder of the sauce over the top of the rolls. Cover with aluminum foil. While you're covering, press down lightly to bind the ingredients. Tuck in the refrigerator for four hours or even better - overnight.

Step 5

Remove the pan from the refrigerator and allow the casserole dish to come to room temperature for 15 minutes. Before baking loosen the foil from the top of the buns (that way they do not stick when you remove the foil after baking).

Step 6

Preheat the oven to 350 degrees. Bake for 30 minutes. Remove the pan from the oven. Remove the foil and return the pan back to the oven and bake for an additional 5 minutes.
