In a large bowl, combine the chicken with all the marinade ingredients, coating the chicken evenly, then set aside.
Prepare the pico de gallo by placing all the ingredients in a bowl. Mix well and set aside.
Make the chipotle mayo by placing all the ingredients in a medium bowl and mixing to combine with a spoon. Set aside.
Heat a large, heavy-based pan over medium–high heat. Add the chicken and cook for 6–8 minutes, stirring occasionally to prevent the marinade from burning. Add 1–2 tablespoons of water as needed to help scrape up any sticky bits on the bottom of the pan.
Divide the rice and chicken among four bowls. Top with mashed avocado, corn, black beans, corn chips, pico de gallo and jalapeno slices (if using). Drizzle with the chipotle mayo to serve and an extra squeeze of lime, if desired.
