The main ingredient in tabbouleh is bulgur wheat, which is a whole grain made from cracked wheat. Tabbouleh is a popular Middle Eastern salad that combines bulgur with finely chopped parsley, tomatoes, mint, onions, and seasoned with olive oil, lemon juice, salt, and pepper. Bulgur serves as the base, and its nutty flavor complements the freshness of the herbs and vegetables, making the dish both nutritious and flavorful. Tabbouleh is often served as part of a mezze platter or as a refreshing side dish.
