In a medium bowl, whisk together olive oil, 1 tablespoon lime juice, cumin, garlic powder, salt, pepper, and 1 tablespoon of cilantro.
Add chicken pieces to the marinade, tossing to coat, and let marinate for 10 minutes.
Heat a large non-stick skillet over medium-high heat and cook chicken until internal temperature reaches 165 degrees Fahrenheit, approximately 8 to 10 minutes.
In a separate bowl, combine the cooked rice with the remaining 2 tablespoons of lime juice and the remaining cilantro.
Divide the cilantro lime rice equally among four serving bowls.
Top each bowl with equal portions of cooked chicken, black beans, corn, avocado slices, and pico de gallo.
Serve immediately or store in airtight containers for refrigerated meal prep.
