The Bombay Sandwich is a masterclass in street-food engineering. It’s a multi-layered marvel that relies on the sharp contrast of fiery green chutney and cooling buttered bread. The secret to an authentic sandwich isn't just the ingredients; it’s the paper-thin slicing of the vegetables and that signature Sandwich Masala that ties the earthy potato and crisp cucumber together. It’s the ultimate lunch for when you want something substantial but don't want to turn on the stove for more than a few minutes.
4 slices of white or whole-wheat bread 1 large boiled potato, thinly sliced 1 cucumber and 1 tomato, thinly sliced 1 small red onion, cut into rings The Green Chutney: 1 cup cilantro, 1/2 cup mint, 2 green chilies, a squeeze of lime, and a pinch of salt (blended until smooth) Salted butter and Sandwich Masala (or Chaat Masala)
Generously butter two slices of bread. Apply a thick layer of the green chutney over the butter; the butter acts as a barrier so the bread doesn't get soggy.
Layer the potato slices first, followed by a sprinkle of masala.
Stack the cucumber, tomato, and onion rings. Sprinkle more masala between every layer to ensure every bite is seasoned.
Close the sandwich and trim the crusts if you’re going for that classic street-vendor look. Slice into six small squares and serve with extra chutney.
