Heat a large nonstick skillet over medium heat and add the bacon. Cook until crispy and fat is rendered, then remove the bacon with a slotted spoon and place it on a paper towel to drain. Add the onions to the skillet and toss to coat in the bacon grease. Cover the skillet, reduce the heat to low and cook until the onions begin to caramelize, about 10-15 minutes, stirring occasionally while cooking. Stir in the garlic and cook for 30 seconds, then remove the onions and the garlic and place them in a bowl.

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.
