Season the chicken breast evenly on both sides with sea salt, black pepper, and garlic powder.
Heat the extra virgin olive oil in a medium skillet over medium-high heat until shimmering.
Place the chicken in the skillet and sear for 6 to 7 minutes per side until the exterior is golden brown and the internal temperature reaches 165 degrees Fahrenheit.
While the chicken is cooking, dice the avocado, halve the cherry tomatoes, and finely chop the red onion and cilantro.
In a small mixing bowl, toss the avocado, tomatoes, onion, cilantro, and lime juice together to create the fresh salsa.
Warm the black beans in a small saucepan over low heat or in a microwave-safe dish until heated through.
Transfer the cooked chicken to a plate, top generously with the avocado salsa, and serve with the warm black beans on the side.
