Add the chicken breast, onion, garlic, salsa, chicken broth, chili powder, cumin, oregano, cayenne pepper, salt, and pepper to the slow cooker. Stir together and cook on low for 4 hours or until chicken is cooked through. Slow cookers cook at different rates so check the chicken at 3 hours so it won't overcook.

Add the chicken back to the slow cooker. Stir in the rice and black beans. Turn the slow cooker up to high and cook for 35-40 minutes until the rice is cooked through and has absorbed most of the liquid. Season with salt and pepper as needed. Serve with all your favorite toppings.
