Place chicken and BBQ sauce in a slow cooker and stir to coat the chicken. Cook on high for 2.5-3 hours. Shred chicken and return to the slow cooker, stir and keep warm until ready to serve.
Marinate chicken in BBQ sauce for 1 hour, grill over medium high heat for 6-8 minutes per side, until the internal temperature reaches 165 degrees F. Let rest for 5 minutes and cut into strips or bite-sized pieces.
In a pot, bring quinoa and water to a boil. Reduce heat to low, cover, and cook for 15 minutes. Fluff and keep covered for 10 more minutes.
In each bowl, add 3/4 cup of quinoa. Top with shredded chicken, black beans, cabbage, corn, red onion, tomatoes, jalapenos, and avocado. Drizzle with ranch dressing and garnish with cilantro and scallions. Enjoy!
