To a large bowl, add the salad greens, cooked chicken, cooked quinoa, drained chickpeas, bell pepper, tomatoes, cucumber, the 1 cup feta cheese, kalamata olives, and red onion.
To a small bowl or jar with a tight-fitting lid, add the vinaigrette dressing ingredients (the ¼ cup olive oil through the black pepper). Whisk together or shake well.
Pour the dressing over the salad and toss until evenly coated.
If desired, top servings with dollops of hummus, roasted chickpeas, and/or fresh herbs.
