Prepare the quinoa or brown rice as directed on the package.
Sprinkle salt, pepper, and a small amount of olive oil over the chicken breast. Cook in a skillet over medium heat until no longer pink.
Place corn and red bell pepper into the same skillet; sauté for 5-7 minutes.
In a large bowl, mix together the cooked quinoa or rice, sautéed corn and peppers, diced avocado, and chopped cilantro.
Drizzle lime juice over the mixture and toss to combine.
Cut the chicken into slices and arrange on top of the corn mixture. Enjoy!
