I have consistently read that the best salad dressing that you can use for your salads is vinegar and oil based dressing. Here is one I found in a book called The Diabetes Improvement Program by Patrick Quillin. This is an excellent recipe. Give it a try and see.

Royal Salad Dressing

¼ cup each of apple cider vinegar, flax oil, olive oil, and water
1 package dry Italian Salad Dressing mix
1-2 teaspoons liquid lecithin

Add all the ingredients together in a jar (use a lid, LOL) and shake it vigorously. Be sure to keep it refrigerated, preferably in a dark part of the refrigerator.

Enjoy!
