Add the pulled pork, Ro-tel, chipotle peppers, barbecue sauce, chicken base, oregano, cumin, and onion powder to a large pot or Dutch oven over medium-high heat. Cook until ingredients are simmering.
Add the beans and rice and heat through. Stir gently as needed. Once hot, remove from heat, add the cheese, and fold in. Add lid to allow cheese to melt.
Serve as desired in tacos, burritos, or bowls.
