Dice the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Heat the olive oil in a medium pot over medium heat and sauté the diced red onion and bell pepper until they begin to soften.
Add the chicken pieces to the pot and cook for 3-4 minutes until the exterior is lightly browned.
Stir in the chili powder, cumin, and garlic powder, ensuring the chicken and vegetables are thoroughly coated.
Add the crushed tomatoes, rinsed black beans, and water to the pot, stirring well to combine.
Bring the mixture to a boil, then reduce the heat to low and cover with a lid.
Simmer for 15 to 20 minutes to allow the flavors to meld and the chicken to reach a tender consistency.
Remove from heat and garnish with fresh chopped cilantro before serving in a warm bowl.
