A potato slider. The vada pav is a popular street food found in every nook and corner of Bombay.This all-time favourite snack of all Mumbaikars is made with deep fried spiced potato dumplings which are covered with besan (gram flour) batter. The vada is placed inside a bread bun (pav) precisely sliced almost in half through the middle. Our vada pav comes with tangy chutneys and a fried green chili pepper.
