Preheat your oven to low broil. Slice the submarine rolls lengthwise without cutting all the way through. Place the rolls cut side up on a parchment-lined baking sheet.

In a medium bowl, combine melted butter, minced garlic, chopped parsley, and salt. Brush the garlic butter onto the cut sides of the rolls.

Broil the rolls for 2-3 minutes until lightly golden and crispy. Remove them once they achieve the perfect color.

Chop the pulled pork, sliced ham, pickles, and Swiss cheese. Mix these ingredients with yellow mustard in a large bowl.

Fill the toasted rolls with the mixture and serve immediately.
