This is one the most colorful and beautiful salads I have ever made. It is full of anti-oxidants, vitamins and is also low carb. You absolutely cannot substitute the sauce...it makes the salad. It is made locally near where I live so I don't know how widely distributed it is...but they have a website to check the nearest place you can find it. There website is www.dulcetcuisine.com. It is an all natural sauce with no preservatives. Preparation of this salad is made very simple if you have a Cuisineart food processor. I made mine without bean sprouts and snap peas, as I did not have them on hand and it was wonderful. The recipe says that it serves 2, but my husband and I both had two bowls for dinner and had at least 3 servings left over.
