What is the best street food in Vietnam? What makes up the best Bánh Mì in Vietnam? Can I make them at home? These are some of the questions leading us to create "Battle of the Banh Mi."

Vietnamese baguette sandwiches, called Banh Mi, have attracted a loyal fan base like never before. Like a musical band with rock star status, these sandwiches have an almost cult-like following of epicurean devotees. The uniqueness of these sandwiches not only lies within the French influenced baguette, but it’s also the flavor packed, savory Viet fillings that what makes the marriage of the two main ingredients a true love affair.
Bánh mì has long been a food staple of the working poor. Bánh mì stalls and carts are everywhere in the streets of Vietnam, providing simple and delicious sustenance, typically for breakfast or the midday meal, to the masses. It was street food long before street food became an obsession with foodies—in those days, some well-to-do Vietnamese shunned street vendors out of concern about typhoid fever and other illnesses. Ingredients like the sweet, crunchy fresh vegetables and pungent herbs and spices are what make the bánh mì Vietnamese. An essential component of the Vietnamese way is Maggi sauce, a Swiss-made savory seasoning introduced by the French.
