Pat the chicken breast dry and season both sides evenly with chipotle powder, cumin, garlic powder, sea salt, and black pepper.
Heat the olive oil in a medium skillet over medium-high heat until shimmering.
Place the chicken in the skillet and sear for 5 to 7 minutes per side, or until the internal temperature reaches 165°F.
Remove the chicken from the pan and let it rest for 5 minutes before slicing into bite-sized cubes.
In the same skillet, add the cauliflower rice and sauté for 3 to 4 minutes until tender and lightly browned.
Warm the rinsed black beans in a small saucepan over low heat or in the microwave for 45 seconds.
Build the bowl by layering the cauliflower rice at the base, followed by the black beans and diced chicken.
Top with the sliced avocado, fresh cilantro, and a bright squeeze of lime juice before serving.
