Sumac chicken is a flavorful and aromatic Middle Eastern dish. The chicken is marinated in a mixture of sumac, lemon juice, garlic, and olive oil, which gives it a tangy and citrusy flavor. It is then grilled or roasted to perfection, resulting in juicy and tender meat with a crispy skin. This dish is perfect for a summer barbecue or a weeknight dinner, and can be served with a side of rice or salad.
