Horiatiki
Greek salad or horiatiki salad[a] [c] is a salad in Greek cuisine generally made with pieces of tomatoes, cucumbers, onion, feta cheese, and olives (typically Kalamata olives) and dressed with salt, Greek oregano, lemon juice and olive oil. Common additions include green bell pepper or caper berries (especially on the Dodecanese islands). Greek salad is often imagined as a farmer's breakfast or lunch, as its ingredients resemble those that a Greek farmer might have on hand. Outside Greece, "Greek salad" may be a lettuce salad with Greek-inspired ingredients, even though the original dish is distinguished by the absence of lettuce. Meanwhile, the variant without lettuce may be called horiatiki, 'peasant salad', or 'village salad'. However in most European countries, including the UK, the dish broadly resembles the original, albeit often with non-Greek substitutions such as another cheese since feta cheese enjoys protected designation of origin status.
