A true Greek salad, or Horiatiki, is a masterclass in ingredient quality rather than complexity. In Greece, you won’t find a single leaf of lettuce; instead, the focus is on sun-ripened tomatoes and high-phenolic olive oil. The salad creates its own “dressing” as the salt draws the juices out of the vegetables, mingling with the oregano to form a savory nectar at the bottom of the bowl.
