In a large skillet, heat the olive oil over medium heat. Add the corn kernels and sauté for about 5 minutes until they are slightly charred.
Stir in the chili powder, garlic powder, cumin, salt, and pepper. Cook for an additional 2 minutes to combine the flavors.
In a large bowl, combine the cooked rice and shredded chicken. Mix in the sautéed corn mixture until well combined.
To serve, divide the chicken and corn mixture into bowls. Top each bowl with crumbled cotija cheese, diced avocado, and chopped cilantro.
Squeeze fresh lime juice over the top for added flavor.
