Fattoush

Mixed greens, tomato, cucumber, radish, spring onion, and fresh herbs, usually parsley, mint, and purslane: tossed with crisp shards of toasted or fried pita and a sumac-and-lemon dressing finished with olive oil. Sumac is the analytical signal: tart, fruity, faintly woody, distinct from lemon's pure citric acid, and it gives fattoush its character.
