Bánh mì is the Vietnamese sandwich defined by its baguette-style bread.
A bánh mì typically combines a crisp bread roll with fillings such as pâté, mayonnaise, meat, pickled carrot and daikon, cucumber, cilantro, and chili. The bread reflects French colonial influence, while the fillings and seasoning express Vietnamese culinary traditions.
The word bánh mì literally refers to bread, although in many English-language contexts it means the filled sandwich. Common versions include cold cuts, grilled pork, meatballs, chicken, and vegetarian fillings. Regional and vendor differences are substantial, so there is no single universal ingredient list.
Bánh mì became especially prominent in Vietnam during the twentieth century and later spread internationally through Vietnamese migration. It should not be confused with phở, a noodle soup, or bún bò Huế, a spicy noodle dish. The baguette-based sandwich is the specific food identified by the answer.
