Preheat your oven to 400°F (200°C).
Dice the bell pepper and red onion into small, uniform pieces.
In a small bowl, whisk together the tomato puree, minced chipotle peppers, cumin, garlic powder, and sea salt to create the braising sauce.
Heat olive oil in an oven-safe skillet over medium heat and lightly sauté the peppers and onions for 3 minutes until just softened.
Place the chicken breast in the skillet, surrounding it with the sautéed vegetables and the rinsed black beans.
Pour the chipotle-tomato sauce over the chicken and vegetables, ensuring the meat is thoroughly coated.
Bake for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F.
Sprinkle the shredded cheddar cheese over the chicken during the last 5 minutes of baking until it is melted and golden.
Remove from the oven and let the dish rest for 5 minutes to allow the juices to redistribute.
Serve topped with a dollop of Greek yogurt and a sprinkle of freshly chopped cilantro.
