My favorite recipe category: few ingredients, outstanding results! Delightful, healthful, quick and easy to prepare. I strongly recommend that you use only kalamata olives in this recipe. Otherwise I used 9 ounces bagged spinach, 6 ounces pasta myself, but published the recipe as written. From a cookbook called "The Best in the World" by Physicians Committee for Responsible Medicine. This particular recipe came from Au Bar (renamed Je Me Souviens) in Palm Beach, Florida.
