Season the chicken breast evenly with sea salt, black pepper, and garlic powder.
Heat the extra virgin olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-7 minutes until golden brown and cooked through, then remove and set aside.
In the same skillet, add the diced red onion and red bell pepper, sautéing for 3-4 minutes until they begin to soften.
Stir in the black beans and minced chipotle peppers in adobo, cooking for another 2 minutes until the mixture is fragrant and smoky.
While the vegetables cook, lightly steam the cauliflower rice in a separate pan or microwave until tender.
Slice the cooked chicken into bite-sized strips and return it to the skillet to toss with the bean and pepper mixture.
Divide the cauliflower rice into bowls and top with the chipotle chicken and bean mixture.
Garnish each bowl with fresh avocado slices, a squeeze of lime juice, and chopped cilantro before serving.
