Heat olive oil in a skillet over medium heat. Add diced chicken and taco seasoning. Cook until chicken is browned and cooked through, about 7-10 minutes.

In a large pot, combine cooked rice and black beans. Heat over low until warmed through.

In serving bowls, layer the rice and bean mixture, followed by the cooked chicken, corn, cherry tomatoes, lettuce, avocado, and any additional toppings.

Drizzle with lime juice and top with cilantro.
