Rinse quinoa well and bring to a boil in 1.5 cups of water (or broth), lower heat, cover and simmer quinoa for 10 minutes, or until water has absorbed. Remove from heat and set aside
While the quinoa is cooking, heat a pan over medium low heat and add sesame seeds. Toast them by stirring them in the pan until they have slightly browned, watching not to burn them, about 3 minutes. Pour them out into a dish or on a plate
In the same pan over medium low, heat 1 tbsp toasted sesame oil. Add in the sliced onion and celery, stirring until softened, about 5 minutes. Stir in minced garlic until fragrant then stir in the cooked chicken
Whisk dressing ingredients in a large mixing bowl, then add in the chicken mixture and stir well. Add in the cooked quinoa, stir again and serve.
