In a bowl, whisk together the adobo sauce, garlic powder, onion powder, ground cumin, and salt.
Add the chicken breasts and thighs to the bowl and turn to coat evenly in the marinade. Let marinate in the fridge for at least 30 minutes.
Preheat oven to 425°F.
While the chicken is marinating, prepare the vegetables, then toss together with the black beans on a sheet pan with a drizzle of olive oil or cooking spray. Season with garlic powder, paprika, onion powder and cumin.
Place the marinated chicken on a baking sheet. Roast on the top rack in the oven for 20-25 minutes. Place the vegetables on the middle or bottom rack. Roast until the chicken is cooked through and the vegetables are tender and slightly browned. The beans should be lightly crispy.
While they roast, cook the rice according to package instructions. Add it to a large bowl, and mix with chopped cilantro, lime juice, a pinch of salt and a pinch o cumin.
Let the rice cool before packing in a sealed container. Let the chicken and vegetables also cool before packing in a sealed container.
When serving, microwave the rice with the chicken and veggies until warm. Then garnish each bowl with sliced avocado, a dollop of sour cream, and a sprinkle of cheese. Top with herbs.
