Cut the chicken breast into 1-inch cubes and chop the red bell pepper and red onion into similar sized pieces.
In a small mixing bowl, whisk together the extra virgin olive oil, lime juice, chili powder, ground cumin, garlic powder, sea salt, and black pepper to create the marinade.
Place the chicken cubes and chopped vegetables into a bowl, pour the marinade over them, and toss until everything is thoroughly coated; let it marinate for 10 minutes.
Thread the marinated chicken, peppers, and onions onto wooden or metal skewers, alternating between the ingredients.
Preheat a grill or a large non-stick skillet over medium-high heat and cook the skewers for 4-5 minutes per side, or until the chicken is cooked through and the vegetables are slightly charred.
Place the warm cooked quinoa on a plate, top with the skewers, and garnish with freshly chopped cilantro.
