Season the chicken breast evenly with chipotle powder, cumin, garlic powder, sea salt, and black pepper.
Heat the avocado oil in a large skillet over medium-high heat and cook the chicken until golden brown and cooked through.
Remove the chicken from the pan and let it rest for 5 minutes before slicing into bite-sized pieces.
In the same skillet, sauté the diced bell peppers and red onions until they are tender and slightly charred.
Steam or sauté the cauliflower rice until tender and warm the black beans in a small saucepan.
Assemble the bowl by layering the cauliflower rice and black beans at the bottom.
Top with the sliced chicken and sautéed vegetables.
Finish the bowl with fresh avocado slices, a sprinkle of cilantro, and a drizzle of lime juice.
