Clean potatoes and poke with a fork to create a steam vent. Drizzle olive oil and rub the potatoes to fully coat. Sprinkle salt lightly.
Bake potatoes in a 400 degree oven or over indirect heat in your smoker for about an hour until they can be poked tender with a fork.
Allow potatoes to cool for about 10 minutes. Then cut them in half the long way.
Use a spoon to scoop the inside of the potato out leaving about ¼ inch thick of potato still in the shell. Place the potato shells in an aluminum pan.
In a separate bowl combine the leftover pulled pork and barbecue sauce.
Spoon the barbecue pork into each of the potato shells. Top with a sprinkle of shredded cheese.
Return the potato skins to the grill for about 20 more minutes.
Meanwhile, combine the sour cream, chives, scallions, garlic powder, onion powder and salt in a small bowl.
Once the potato skins have finished and the cheese is nicely toasted, remove from the grill. Use the sour cream and onion dip as a topper or a dip.
