Preheat your grill to medium-high heat.

Cut four large pieces of aluminum foil, which will be large enough to wrap the chicken and vegetables completely.

Place each chicken breast in the middle of each of the foil pieces, and surround with ¼ of the sliced bell pepper, ¼ of the onion, ~¼ cup of black beans, and ½ cup of frozen corn.

In a small bowl, whisk together chili powder, cumin, and garlic powder.

Sprinkle each packet the spice mixture, salt, and pepper, and drizzle with olive oil.

Place the packets on the preheated grill and cook for 25-30 minutes, until the chicken is cooked through to 165 degrees F. During the last approximately 5 minutes of cooking time, open each packet and sprinkle with ¼ cup of cheese. Cover and continue the remainder of the cooking time.

Serve topped with chopped cilantro and enjoy!
