Preheat oven to 400 degrees and spray a baking sheet with non-stick spray.
Using a clean cutting board, make 5 or 6 horizontal slits in each chicken breast, without cutting all the way through.
Rub seasoning over chicken breasts. Add more seasoning if desired. Be sure to coat inside of chicken slits.
Stuff chicken slits with julienned bell peppers, and onions generously. While cooking, the peppers and onions will cook down.
Place on baking tray for 20-25 minutes, or until chicken breast is full cooked and internal temperature reaches 165 degrees.
Top with cilantro, avocado, and salsa. Enjoy! Serves well with Spanish or Cauli rice!
