Season chicken breast with sea salt, black pepper, cumin, and chili powder.
Heat olive oil in a large skillet over medium-high heat.
Add chicken to the skillet and cook for 5-7 minutes per side until golden and cooked through.
Remove chicken to rest, then in the same skillet, sauté sliced bell peppers and red onion until tender-crisp.
In a separate pan or microwave, lightly steam the cauliflower rice until softened.
Warm the black beans in a small saucepan over low heat.
Slice the chicken into bite-sized strips.
Build the bowl by layering cauliflower rice, black beans, sautéed peppers, and chicken.
Garnish with avocado slices, fresh salsa, lime juice, and chopped cilantro.
