Season the chicken breast evenly on both sides with half of the sea salt, black pepper, and cumin.
Heat a grill pan or skillet over medium-high heat and lightly coat with a small amount of olive oil.
Cook the chicken for 6-7 minutes per side or until the internal temperature reaches 165°F, then let it rest for 5 minutes before slicing.
While the chicken cooks, rinse and drain the black beans thoroughly.
In a medium mixing bowl, combine the black beans, corn, diced red bell pepper, and finely chopped red onion.
Whisk together the olive oil, lime juice, and the remaining salt, pepper, and cumin in a small jar to create the dressing.
Pour the dressing over the bean mixture, add the fresh cilantro, and toss well to combine.
Slice the rested chicken into strips and serve it over a generous portion of the black bean and corn salsa.
