Directions Add all ingredients to medium bowl and whisk until blended. Alternately, you could use an immersion blender or small food processor- don't blend too long or you will have green ranch. Cover and refrigerate for at least 2 hours if possible. Overnight is even better. Will keep for about 1 week. This recipe makes about 2 cups. 16 servings is based on approx. 2 TBSP per serving.
