Dice the chicken breast into bite-sized pieces and season thoroughly with chipotle powder, cumin, garlic powder, sea salt, and black pepper.
Heat the olive oil in a large skillet over medium-high heat until shimmering.
Add the seasoned chicken to the skillet and sauté until golden brown and cooked through, approximately 6-8 minutes.
Remove the chicken from the pan and set aside; in the same skillet, add the cauliflower rice and sauté for 3-4 minutes until tender and slightly toasted.
Stir the rinsed black beans and half of the lime juice into the cauliflower rice, heating for an additional 2 minutes until warmed through.
Assemble the bowl by portioning the cauliflower rice and bean mixture into a bowl, then topping with the cooked chicken.
Finish the dish with sliced avocado, fresh cilantro, and a final drizzle of the remaining lime juice.
