PIYAZ is a traditional Turkish white bean salad characterized by tender cooked white beans combined with thinly sliced red onions softened in lemon juice and salt, fresh parsley, and seasoned with tart sumac, olive oil, lemon juice, salt, and black pepper. This simple, refreshing salad is perfect as a light side dish or a healthy snack, balancing acidity, richness, and herbal freshness without cooking beyond boiling the beans.
