Preheat oven to 350°.
In a bowl, mix together the bell pepper, onion, corn, tomatoes, and beans. Salt and pepper lightly.
Cut two 10 by 10 squares of aluminum foil. Spray lightly with cooking spray.
Place a chicken breast on each square. On top of a baking sheet (you will need this to catch any liquid that may leak)
Spoon half of the vegetable mixture over the each chicken breast.
Scoop ⅛ cup of chunky salsa or picante on each of the chicken pieces.
Bring two sides of the foil together and fold over twice, refer to photos.
Seal the foil fully and bake for 25 minutes (may need 35 depending on how thick your chicken is)
After the chicken is cooked, open the packets and sprinkle on the cheese and bake for another five minutes, or until the cheese is melted.
Serve and enjoy hot!
