In a medium pot, combine quinoa and water (or chicken broth) and bring to a boil. Reduce heat to low, cover, and let simmer for about 15 minutes, or until all liquid is absorbed. Fluff with a fork and set aside to cool.
While the quinoa cooks, season the chicken breasts with olive oil, chili powder, cumin, salt, and pepper.
In a skillet over medium heat, cook the chicken for about 6-7 minutes on each side, or until fully cooked and the internal temperature reaches 165°F (75°C). Remove from heat and let rest for a few minutes before slicing.
In a large mixing bowl, combine the cooked quinoa, black beans, corn, diced red bell pepper, and diced avocado.
Slice the cooked chicken and add it to the bowl. Then sprinkle with chopped cilantro and garlic powder.
Drizzle lime juice over the entire salad and gently toss to combine all ingredients without mashing the avocado.
Taste and adjust seasoning with more salt, pepper, or lime juice if desired.
Notes
Adjust seasoning to taste and enjoy as a light meal or side dish.
