For an extra layer of flavor, try lightly toasting the sesame seeds before adding the sesame oil to the vinaigrette. Feel free to experiment with other vegetables, such as red onion or bell peppers, to customize the salad to your liking. This salad is best served immediately, but can be stored in the refrigerator for up to 24 hours. If storing, add the dressing just before serving to prevent the vegetables from becoming soggy.
