This recipe was inspired by a sweet potato soup recipe I got from a friend. I modified it to be more in keeping with a Nutritarian eating style. It gets its creaminess from cashew cream. You can reduce prep time by using frozen onion and sweet potato. It is good served hot or cold.....For each can of low sodium broth, I substitute 2 cups water, 1 tablespoon VegiZest (from drfuhrman.com) and 1/8 teaspoon salt (optional).
