Season the chicken breasts with chili powder, paprika, garlic powder, salt, and pepper. Grill over medium-high heat for about 6-7 minutes on each side, or until the chicken reaches an internal temperature of 165°F. Once cooked, let them rest for a few minutes before slicing.
In a large bowl, combine the sweet corn, diced red bell pepper, chopped cilantro, and lime juice. Toss everything gently to mix well, and add salt and pepper to taste.
In each serving bowl, create a base by adding the cooked brown rice (or quinoa) first. Top with sliced chicken breast and then the corn mixture.
Add diced avocado and sprinkle crumbled cotija cheese over the top. Drizzle a little olive oil for added flavor.
Enjoy your Mexican street corn chicken bowls while everything is fresh and warm!
Notes
Feel free to substitute quinoa for a lighter option.
