The Essence Of Banh Mi The taste of Banh Mi is like Vietnam itself: bold and unique. This flavorful sandwich had to capture the attention of the busy motorbikers driving by on the crowded streets of Vietnamese cities. Designed to be quick, convenient, and easy to carry, banh mi never lost one important characteristic: flavor. These sandwiches were so delicious and so popular that Vietnamese cities saw the rise of tiny tables and chairs alongside busy streets, where customers could sit and enjoy banh mi while taking in the iconic sites of Vietnam. The secret to a good banh mi sandwich is fresh ingredients that are free from trans fats. Inspired by the French Colonial period, when France occupied Vietnam, the banh mi began as a combination of locally found Vietnamese meats and vegetables stuffed into a French baguette. The resulting sandwich exploded in popularity. Since then, it has become the essence of the Vietnamese urban cuisine dining experience. Rooted in the simplicity and richness of the Vietnamese culture, banh mi continues to win new fans as demand for it spreads throughout the world.
