Cook the rice to package directions.
Heat 2 tbsp of the olive oil in a 12 inch cast iron skillet over medium heat. Add the chicken breast, seasonings and lime juice. Cook 3-4 minutes each side until cooked through. Remove the chicken from the skillet and transfer to a plate. DO NOT rinse the skillet.
Add the remainder of the olive oil to the skillet (2 tbsp) and saute the onions for 3 minutes. Add the bell peppers and saute another 4 minutes. Add the corn, black beans and olives. Cook another 3 minutes until hot. Mix in 1/4 cup chopped cilantro. Add the chicken back into the pan and cook 2 minutes.
Plate the rice into bowls. Top with the chicken mixture. Top with any additional toppings you desire. Serve immediately.
