To cook potatoes, pierce all sides with a fork or knife to allow steam to escape. You can either bake at 400 degrees F for 1 hour, or use a pressure cooker on high pressure for 25 minutes and manual release the pressure.
Once potatoes are cooked, allow to cool for a bit to be able to handle without burning your hands.
Once cooled slighltly, slice in half lengthwise.
With a spoon, scoop out the middle of the potatoes into a bowl. You should have the potato skins left that look like a little bowl. Place the skins on to a baking sheet or in a glass baking dish.
Mix the inside of the potatoes that you have scooped into a bowl with butter, milk (start with 1/4 cup and add more if needed), salt, pepper, garlic, and half of the shredded cheese. Mix until a smooth consistency, adding more milk if needed.
Spoon filling back into the potato skins.
Top each potato with pork.
Sprinkle cheese and drizzle barbecue sauce over the top.
Bake at 400 degrees F for 25 minutes, or until heated through.
Garnish with parsley and serve. Enjoy!
