In a 2 cup pyrex measuring cup (or small bowl) combine dressing ingredients. Use a whisk to thoroughly combine ingredients.
In a large bowl, combine salad ingredients and toss. OR toss greens, onions, celery and carrots and keep chicken and mango separate.
Then either mix all of the salad ingredients and toss them with the dressing OR build individual salads by placing greens in a bowl, topping with chicken and mangoes, and then drizzling dressing over the salad.
