Season the chicken breast evenly with sea salt, black pepper, and garlic powder.
Heat olive oil in a large skillet over medium-high heat and sear the chicken until golden brown and cooked through, about 6 minutes per side.
Transfer chicken to a cutting board, let it rest for 5 minutes, then dice into bite-sized pieces and toss with the minced chipotle peppers.
In the same skillet, sauté the sliced bell peppers and red onion for 4-5 minutes until they are tender and slightly charred.
Steam or lightly sauté the cauliflower rice in a separate pan until tender, and warm the rinsed black beans.
Build the bowl by layering the cauliflower rice and black beans at the base.
Top with the sautéed peppers, onions, and chipotle chicken.
Garnish with fresh avocado slices, chopped cilantro, and a bright squeeze of lime juice before serving.
