In a large mixing bowl, combine the shredded chicken, corn kernels, mayonnaise, lime juice, chili powder, and half of the cotija cheese. Stir until fully blended.

Add salt and pepper to taste. Set the mixture aside.

Evenly divide the cooked rice among four serving bowls.

Spoon the prepared chicken mixture over the rice in each bowl.

Garnish each bowl with avocado, remaining cotija cheese, red onion, and cilantro.

Serve immediately with extra lime wedges.
