 This dish combines salad vegetables such as cucumber, tomato, bell pepper, and onion with a mixture of pineapple (or pear), vinegar, and sugar to make a cold served dish.In China traditionally the sauces are made from mixing sugar or honey with a sour liquid such as rice vinegar, soy sauce, and spices such as ginger and cloves.Sometimes a paste made from tomatoes is used but this is rare and normally restricted to western cooking.
