In a large bowl, combine the diced chicken breast with olive oil, smoked paprika, cumin, garlic powder, salt, and pepper. Mix well to coat the chicken evenly. Allow it to marinate for at least 15 minutes.
In a medium saucepan, bring 2 cups of chicken broth to a boil. Stir in the rinsed quinoa, reduce heat to a low simmer, cover, and cook for about 15 minutes or until the liquid is absorbed. Fluff with a fork and set aside.
While the quinoa cooks, heat a large skillet over medium-high heat. Add the marinated chicken and cook for approximately 6-8 minutes, stirring occasionally, until the chicken is cooked through and no longer pink in the center.
Add the diced red bell pepper and corn to the skillet with the chicken. Cook for an additional 3-4 minutes until the peppers are tender.
Stir in the black beans and cooked quinoa into the chicken and veggie mixture. Cook for another 2 minutes, just to heat through. Taste and adjust seasoning if needed.
Divide the chicken, quinoa, and veggie mixture evenly among your meal prep containers. Top each serving with slices of avocado.
Squeeze fresh lime juice over the top and sprinkle with chopped cilantro if desired. Close the containers and store them in the refrigerator.
