Chicken Shawarma ingredients - A common street food dish in the Middle East, chicken shawarma is renowned for its strong, savoury tastes and fragrant spices. It consists of thin marinated chicken slices that are stacked on a vertical rotisserie (or grilled or pan-cooked at home), shaved off, and usually served with fresh veggies and creamy sauces like tahini or garlic sauce over a warm pita or flatbread.
