Season the chicken breast evenly with half of the ground cumin, chili powder, sea salt, and black pepper.
Heat a grill pan or cast-iron skillet over medium-high heat and cook the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
While the chicken is cooking, rinse and drain the black beans thoroughly.
In a medium mixing bowl, combine the black beans, corn, diced red bell pepper, and finely minced red onion.
In a small jar or bowl, whisk together the extra virgin olive oil, lime juice, and the remaining spices to create the dressing.
Pour the dressing over the bean and corn mixture, add the chopped fresh cilantro, and toss well to combine.
Remove the chicken from the heat, let it rest for 3 minutes, then slice it into strips.
Serve the sliced grilled chicken immediately alongside the chilled salsa for a fresh and protein-packed meal.
