Season the chicken breast evenly with the cumin, sea salt, and black pepper.
Heat a skillet over medium heat with half of the olive oil and cook the chicken until golden and cooked through, approximately 6 to 7 minutes per side.
While the chicken is cooking, thoroughly rinse and drain the black beans in a fine-mesh sieve.
Dice the avocado, bell pepper, and red onion, and slice the cherry tomatoes in half.
In a large mixing bowl, whisk together the remaining olive oil, lime juice, and chopped cilantro to create the dressing.
Once the chicken is finished, let it rest for a few minutes before slicing into bite-sized strips.
Add the chicken, black beans, avocado, tomatoes, peppers, and onion to the bowl with the dressing and toss gently to combine.
