Hiyashi chūka is made with cold Chinese-style egg noodles, with sweet vinegar sauce topped with vegetables, egg and meat. It is a great dish to have on a hot summer day. The instructions are long because I have explained the preparation of toppings in detail. But it is actually quite fast to make and minimal cooking is required. You can vary the toppings if you like. Please see note 5 for suggested toppings.
