Heat the olive oil in a large cast-iron or stainless steel skillet over medium-high heat until shimmering.
Add the ground chicken to the hot skillet, using a wooden spoon to break it into small crumbles, and cook for 5-6 minutes until fully browned.
Incorporate the diced red bell pepper, yellow onion, and minced jalapeño, sautéing for another 4 minutes until the onions are translucent and fragrant.
Stir in the rinsed black beans, salsa, chili powder, ground cumin, sea salt, and black pepper, ensuring the chicken and vegetables are evenly coated.
Reduce the heat to medium-low and allow the mixture to simmer for 5 minutes, allowing the liquid from the salsa to reduce and the flavors to intensify.
Remove the skillet from the heat and garnish with the freshly chopped cilantro before serving warm.
