In a blender, combine the garlic cloves, cumin, black pepper, salt, oregano, orange juice, and lime juice. Blend on high speed until smooth.
Pour the marinade into a large zip top plastic bag and add the pork tenderloin, massaging to coat well. Seal the bag and marinate in the refrigerator for at least 2 hours, up to overnight.
Preheat the oven to 500°F (260°C).
Transfer the pork to a roasting pan and roast until a crust begins to form and the internal temperature reaches 145°F (63°C) , about 20 minutes. Remove from the oven and let the pork rest for at least 10 minutes before carving (if you have time, you can refrigerate the pork overnight so it’s easier to slice).
Cut 15 slices from the pork tenderloin, reserving any leftovers for another use.
Make the sliders: Reduce the oven temperature to 350°F (180°C). Line a baking sheet with parchment.
Place the bottom halves of the slider rolls on the baking sheet and layer with the ham, pork, salami, Swiss cheese, and pickles.
Slather the inside of the top halves of the rolls with the mustard, then place on top of the sliders. Brush the tops with melted butter.
Bake the sliders until the top turns golden brown and the cheese is completely melted, about 10 minutes.
Pull the sandwiches apart and serve.
