Season the chicken with the salt, pepper, paprika and onion powder. Add it to the same skillet over medium-high heat and cook until it is browned and golden on all sides, about 10 minutes. Once the chicken is cooked through, stir in 1/3 cup of the BBQ sauce and reduce the heat to low. Add in the cooked quinoa, onions, chickpeas, corn, red peppers and half of the cilantro and green onions. Toss well to mix. Right before serving, stir in the bacon, reserving a little bit for topping. Serve and garnish with the remaining cilantro, green onions and bacon.
