When I first saw a recipe for Peanut Butter Soup I wasn't sure how it would be but I decided to give it a try since I love peanut butter. What a pleasant surprise! This version is adapted from Jane Brody's "Good Food Book" modified to be more in keeping with a Nutritarian eating style.....For each can of low sodium broth, I substitute 2 cups water, 1 tablespoon VegiZest (from drfuhrman.com) and 1/8 teaspoon salt (optional).
