Another classic of Chinese cuisine, Guangdongese lo mein or laomian (lit. stirred noodles) refers to any kind of dish made with separately boiled wheat and egg noodles which are then tossed in a savory sauce and mixed with various stir-fried vegetables or meats.
When cooked properly, lo mein should be springy and have a firm bite to them, just like Italian pasta or Japanese ramen. For that strong kick of umami, the Chinese typically flavor their lo mein dishes with sesame oil, green onions, ginger, and oyster or soy sauce.
