Set up a top-your-own potato bar at your next family movie or game night.
Preheat oven to 400°F. Place potatoes on an aluminum foil-lined large rimmed baking sheet. Bake in preheated oven until very tender, about 45 minutes.
Meanwhile, heat oil in a large skillet over medium. Add onion slices, and cook, stirring often, until tender and lightly browned, 5 to 7 minutes. Add bell pepper, and cook, stirring often, 5 minutes. Remove from heat, and sprinkle with salt and black pepper.
Cut a lengthwise slit down center of each potato (do not cut all the way through); squeeze sides to open. Slightly mash cooked potato pulp, and push toward opening. Top with cheese, pork, onion mixture, corn chips, and avocado; drizzle with barbecue sauce, and sprinkle with cilantro.
Toss together coleslaw mix and white barbecue sauce; serve with pork-stuffed potatoes.
