Vada pav

Vada pav, alternatively spelt wada pao, is a vegetarian fast food dish native to the Indian state of Maharashtra. The dish consists of a deep fried potato dumpling placed inside a bread bun (pav) sliced almost in half through the middle. It is generally accompanied with one or more chutneys and a green chili pepper. Although it originated as an affordable street food in Mumbai, it is now served in food stalls and restaurants across India. It is also called Bombay burger in keeping with its origins and its resemblance in physical form to a burger. The most famous snack in Mumbai, vada pav is claimed to be a part of the culture of Mumbaikars.
