One bite and I guarantee you will declare bánh mì - the Vietnamese sandwich and street food staple - a triumph of rich, sweet, spicy, tangy, herbaceous deliciousness. And what's not to love? Traditionally made with a light French baguette (a vestige of Vietnam's French-colonial history), pickled carrot and daikon, spicy chili sauce, mayo, cilantro, cucumbers, and a richly flavored proteinous filling, the bánh mì is a category of flavor combinations unto itself. The beauty of the bánh mì (which actually only means "bread" in Vietnamese, although the term has come to be associated with the sandwich) is in its ability to accomodate a range of fillings - from steamed, roasted, or grilled meats to tofu, even eggs. Included below is a recipe for chicken meatballs.
