Overseas Vietnamese
The baguette was introduced to Vietnam by the French in the mid-19th century, when Vietnam was under the Nguyễn dynasty, and became a staple food by the early 20th century. During the 1950s, a distinctly Vietnamese style of sandwich developed in Saigon, becoming a popular street food, also known as bánh mì Sài Gòn (""Saigon sandwich", "Saigon-style banh mi""). Following the Vietnam War, Overseas Vietnamese popularized the sandwich in countries such as Australia, Canada and the United States. In these countries they are commonly sold in Asian bakeries.
