This recipe is one of a number of cold snacks (known as بوارد, bawārid) found in what is thought to be the earliest cookery manual (10th century). These cold dishes were served prior to the main course and eaten with bread. This particular dish is highly nutritional as well as very simple to make. It requires gourd, chard, mallow and purslane added with sweet yoghurt, mixed with ground mustard and olive oil. Though not in the original recipe, it seemed a good idea to decorate with some freshly sliced cucumber! It is wonderful with some crusty bread and makes for a perfect picnic dish!
