Place the chicken breasts in an even layer across the bottom of a 6 to 7-quart (5.7 to 6.6 L) slow cooker. Keeping the chicken in a single layer helps it cook at a similar rate.
2 lbs (907 g) boneless, skinless chicken breasts
Add the diced onion, salsa, black beans, undrained diced tomatoes, undrained green chiles, chicken broth, chipotle chile powder, paprika, oregano, salt and black pepper. Cover and cook on LOW for 4 hours, or until the chicken reaches an internal temperature of 165°F (74°C) and is tender enough to shred easily.
1 medium yellow onion, 1 (16 oz / 454 g) jar salsa , 1 (15 oz 425 g) can black beans, 1 (10 oz / 283 g) can diced tomatoes, 1 (4 oz / 113 g) can diced green chiles, 2 cups (473 ml) low-sodium chicken broth, 1 tsp (2 g) chipotle chile powder , 1 tsp (2 g) paprika, 1 tsp (1 g) ground oregano, 1 tsp (6 g) table salt, 1 tsp (2 g) finely ground black pepper
Transfer the chicken to a large bowl and shred it with two forks or meat shredders. Keep the slow cooker covered while you shred the chicken so the cooking liquid stays hot. The retained heat is important because the instant rice is added next and cooks directly in this liquid.
Return the shredded chicken to the slow cooker and add the uncooked instant white rice. Stir well, making sure the rice is distributed throughout the chicken mixture and in contact with the hot cooking liquid rather than sitting dry on top.
2 cups (370 g) instant white rice
Cover and continue cooking on LOW for about 45 minutes. Check the rice for tenderness before moving on. It should be tender and most of the cooking liquid should be absorbed, although the exact timing can vary between slow cookers.
Sprinkle the shredded Colby-Jack cheese evenly over the chicken burrito bowl mixture. Cover and cook for another 3 to 5 minutes, or until the cheese is completely melted.
8 oz (227 g) shredded Colby-Jack cheese
Spoon the slow cooker chicken, black bean and rice mixture into individual bowls and serve hot with your preferred burrito bowl toppings.
