Kleftiko is a traditional Greek meat dish that is popular in Heraklion. It is made with tender pieces of lamb or goat, marinated in olive oil, lemon juice, garlic, and herbs, and then slow-cooked in a sealed clay pot until the meat is tender and falls off the bone. The result is a flavorful and succulent meat dish that is often served with roasted potatoes and a side of tzatziki sauce.
