Pat the chicken breast dry with paper towels and season both sides evenly with sea salt, black pepper, and garlic powder.
Heat the olive oil in a large non-stick skillet over medium-high heat until shimmering.
Place the chicken in the skillet and sear for 5 to 7 minutes per side until a golden crust forms and the internal temperature reaches 165 degrees Fahrenheit.
Remove the chicken from the pan and set it aside on a plate to rest for 5 minutes.
In the same skillet, add the sliced red bell peppers and red onion, sautéing for 3 to 4 minutes until they are tender-crisp and slightly charred.
Stir in the rinsed black beans, smoked paprika, and ground cumin, cooking for another 2 minutes until the beans are heated through.
Turn off the heat and stir in the fresh lime juice, scraping up any browned bits from the bottom of the pan.
Slice the rested chicken breast into strips and serve it over the smoky bean and pepper mixture, garnished with chopped fresh cilantro.
