Preheat a grill to medium-high heat or prepare a campfire with a bed of hot coals.
In a large bowl, combine the chicken, bell peppers, onion, black beans, and corn.
Drizzle with olive oil.
Add the chili powder, cumin, smoked paprika, garlic powder, onion powder, pepper, and salt. Toss until everything is evenly coated.
Tear six large sheets of heavy-duty aluminum foil.
Divide the chicken mixture evenly among the foil sheets.
Fold and seal each packet tightly.
Place the packets on the grill or over indirect campfire heat.
Cook for 18–22 minutes, turning once halfway through cooking.
Carefully open the packets and check that the chicken has reached an internal temperature of 165°F.
Sprinkle each packet with shredded cheese.
Close loosely for 1–2 minutes until the cheese melts.
Add desired toppings and serve directly from the packets.
