Spread mayonnaise onto bottom half of rolls, and top each with 1 slice ham, 2 pieces of cheese, 1 piece of bacon, 1 pickle slice, and top half of rolls. Arrange in a 13×9-inch baking dish.
In a small bowl, whisk together melted butter, mustard, poppy seeds, garlic powder, onion powder, and parsley. Drizzle sauce onto rolls; cover with foil.
Bake until cheese is melted, about 20 minutes. Uncover and bake until tops are lightly browned, 3 to 4 minutes more. Serve warm.
Notes
Any thinly sliced deli meat and cheese you already have can be used in place of ham and Swiss.
