In a saucepan, bring water or chicken broth to a boil. Add the rinsed quinoa, reduce heat to low, cover, and simmer for about 15 minutes or until all liquid is absorbed. Remove from heat and let it sit covered for 5 minutes. Fluff with a fork.
While quinoa is cooking, season the chicken breasts with salt and pepper. Heat olive oil in a grill pan or skillet over medium-high heat. Cook the chicken for about 6-7 minutes on each side, or until fully cooked through.
Once the chicken is cooked, brush each piece generously with BBQ sauce and let it sit for a minute to caramelize. Remove from the heat and slice into strips.
In large bowls, layer the cooked quinoa as the base. Top with sliced BBQ chicken, cherry tomatoes, avocado, corn, black beans, and red onion.
Drizzle any remaining BBQ sauce over the top, and sprinkle with fresh cilantro for an added flavor burst. Serve immediately.
Notes
Use homemade or low-sugar BBQ sauce for a healthier option.
