From the Recipe Creator: This fluffy salad is a real treat since it's creamy but not overly sweet. It's easy to mix up, and the flavor gets better the longer it stands. Pistachio salad is perfect for St. Patrick's Day, served in a green bowl. —Pattie Ann Forssberg, Logan, Kansas Sometimes known as Watergate salad, this pistachio fluff is a classic 1970s dessert. However, we think pistachios, pineapple and plenty of fluff create a timeless combination.
