Watercress Green Goddess Dip
Peppery watercress and creamy avocado give this all-purpose dip its spring-green color. Serve with assorted crudités, or thin with water to use as a salad dressing. The dip can be made up to two days ahead.
Blend first 5 ingredients in mini food processor until finely chopped. Add mayonnaise, yogurt, and vinegar, and blend until smooth. Add avocado and blend again until smooth. Season with salt and pepper, if desired. Transfer to bowl. Cover and refrigerate at least 1 hour to develop flavors.
