Bánh mì is a popular Vietnamese variety of sandwiches which shares the same core ingredient, a baguette. The baguette was originally brought over to Vietnam during the colonial period and nowadays it is one of the few happy legacies from that period, the article wrote.

Indeed, the crusty bread, condiments, and meats are all a legacy of French and Chinese colonialism, while cilantro, chili, and pickles reflect the Vietnamese yearning for fresh vegetables with bright flavours.

Most Bánh mì sandwiches originally consisted of bread, meat, and seasoning, and they now have some added vegetables.

TasteAtlas also suggested several famous Bánh mì outlets domestically in Ho Chi Minh City, Hoi An, and Hanoi; and even further afield in the United States and Australia.

The other delicacies to feature in the top five sandwiches in the world include Tombik döner of Turkey, Shawarmas of Lebanon, Tortas of Mexico, and Lobster roll of the US.

The list is based on a vote conducted by experts and readers worldwide on criteria such as popularity, flavour, and love from local people and tourists.
