Dice the apple, strawberries,, and celery to 1/4 inch cubes and place in a bowl
Add splenda to taste to the bowl and toss to mix
Shred the spinach and add it to the bowl
add about 1 TBSP of the dressing to the bowl. Don't over do it. A little dressing goes a long way.
Toss again until well mixed and the dressing coats the ingredients. The xanthan gum helps the dressing cling to the salad, especially after the dressing has chilled in the refrigerator.
Plate the salad on salad plates or bowls, and dress with the berries.
