Chow mein (/ˈtʃaʊ ˈmeɪn/) and (/ˈtʃaʊ ˈmiːn/) 炒麵 in Chinese and Chinese English are stir-fried noodles, the name being the romanization of the Taishanese chāu-mèing. The dish is popular throughout the Chinese diaspora and appears on the menus of Chinese restaurants. It is particularly popular in the United States, UK, Nepal, and India.
