Slice the chicken breast into thin, even strips and set aside.
In a small bowl, whisk together the ground cumin, smoked paprika, garlic powder, sea salt, and black pepper.
Heat the extra virgin olive oil in a large skillet over medium-high heat.
Add the chicken strips to the skillet and toss with the spice mixture, sautéing for 5-6 minutes until cooked through and golden.
Add the sliced bell peppers and red onion to the skillet, cooking for another 3-4 minutes until the vegetables are tender-crisp.
While the vegetables cook, steam the cauliflower rice in a separate pan or microwave until tender.
In a serving bowl, layer the cauliflower rice and rinsed black beans.
Top the base with the sautéed chicken and vegetable mixture.
Drizzle the entire bowl with fresh lime juice and garnish with chopped fresh cilantro before serving.
