While the chicken is being baked, make your moros.
Preheat a large deep non stick frying pan or skillet with olive oil.
Saute the onion, garlic and green pepper until they are soft and transculent.
Add the seasoning - sazon, cumin, oregano, black pepper, pink salt and bay leaves.
Pour in the black beans, brown rice and the water then stir.
Bring the pan to a rolling boil.
Cover with a lid then reduce to simmer on medium-low heat for up to an hour. Keep an eye on the liquid levels, the amount stated should be enough, but you may need to add more (do this ¼ cup at a time) if you reach almost an hour and rice isn't soft enough.10 minutes before the cooking time is over.
Do a taste test and add more pink salt and black pepper, if required.
Place the baked chicken on top of the rice, cover and leave to heat through for the remaining 10 minutes.
Serve accordingly, discard the bay leaves and drizzle the rice and chicken with any leftover liquid.
