Place 2 cups of spinach leaves into each portion container. Place 3.4 ounces of diced fajita chicken in a mound in one corner of the container. In the remaining corners place ¼ cup grapes, ¼ cup shredded carrots, and 1/8 cup celery.
To make the dressing whisk together the Kikkoman Preservative-Free Orange Sauce and the Kikkoman Rice Vinegar. Top salad with 2 tablespoons of the dressing. Alternately, portion 2 tablespoons (1 ounce) of the sauce into portion cups with lids and place inside the salad container.
Top each salad with 1 tablespoon each of green onions, sunflower kernels, and crunchy chow mein noodles. Cover each salad with a lid and hold at or below 40°F until service.
