Mì or mi is a Vietnamese term for yellow wheat noodles. It can also refer to egg noodles. They were brought over to Vietnam as wonton noodles by Chinese immigrants. The Vietnamese version of wonton noodles is mì hoành thánh. The noodles can be either thin or wide and are commonly used in súp mì (noodle soup) and mì khô (dry noodles).
Súp mì or mì noodle soup can be served with a pork-based broth with the noodles and other ingredients together or with the soup served separately. Common ingredients are noodles, pork broth, ground pork, chives and a choice of meats or toppings. They can be served with spicy pickled green papaya (đu đủ chua ngọt) on the side. Condiments may include soy sauce, sa tế, pickled jalapenos, and red or white vinegar.
