Cut each pepper in half and remove the seeds. Stuff peppers with cheese; set aside.
Combine the seasonings; rub over pork. Grill, covered, over medium-hot heat until a thermometer reads 145°, about 15 minutes. Place peppers over indirect heat; cook until peppers are tender and cheese is melted, about 8-10 minutes.
Wear disposable gloves when cutting hot peppers; the oils can burn skin. Avoid touching your face.
