In a small bowl, whisk together the minced chipotle peppers, cumin, garlic powder, sea salt, and black pepper.
Rub the spice mixture evenly over both sides of the chicken breast to ensure full flavor coverage.
Heat the olive oil in a large skillet over medium-high heat.
Place the chicken in the skillet and sear for 5-7 minutes per side until the exterior is charred and the internal temperature reaches 165°F.
Remove the chicken from the pan and let it rest for 3 minutes before slicing into thin strips.
In the same skillet, add the cauliflower rice and sauté for 3-4 minutes until tender-crisp, scraping up any browned bits from the chicken for extra flavor.
Warm the black beans in a small saucepan or microwave until heated through.
To assemble, layer the cauliflower rice in a bowl, top with the black beans, sliced chicken, and avocado slices.
Drizzle with fresh lime juice and garnish with chopped cilantro for a bright, clean finish.
