In a large bowl, combine the orange juice, olive oil, cilantro, garlic, cumin, paprika, salt, and black pepper. Add the chicken thighs and marinate for at least 30 minutes, or up to 2 hours in the refrigerator for more flavor.
In a medium saucepan, bring the chicken broth to a boil. Add the rice, reduce heat to low, cover, and simmer for about 18-20 minutes, or until the rice is tender and the liquid is absorbed.
While the rice is cooking, heat a large skillet over medium-high heat. Remove the chicken from the marinade and add it to the skillet. Cook for about 6-7 minutes on each side, or until the chicken is cooked through and has a nice golden color.
Once the chicken is cooked, remove it from the skillet and let it rest for a few minutes before slicing.
In the same skillet, add the black beans, red onion, and bell pepper. Cook for about 3-4 minutes, stirring occasionally, until the vegetables are tender.
Fluff the cooked rice with a fork and serve it on plates. Top with the black bean mixture and sliced chicken. Garnish with avocado slices and lime wedges.
