DIY Mumbai Sandwich
The Mumbai grilled sandwich at Mumbai Xpress was first brought to my attention by Eating in Translation, and a few visits to the Mumbai street food restaurant made it obvious that the place deserved to get a full review.
But if you want to try the sandwich (alternatively called a Mumbai or Bombay sandwich, or just "chutney sandwich") without a trip to Floral Park, you can easily make it at home. My husband's grandmother used to whip them up often as a quick snack or lunch, and although the classic is a double-decker, you can make it a single-decker (or quadruple-decker!) if you prefer.
Homemade Bombay sandwiches are on my mind because I came across this (above) jar of "Bombay sandwich spread" at India Bazaar (69 First Avenue), and although I really like it, it's one of those things that you don't really need--like peanut butter and jelly swirled together in one jar. It's got all the goodness of a bunch of different chutneys in one: mint, coriander, coconut, green chiles and tamarind. So instead of spreading your sandwich with coriander and green chile chutneys, you can just use this.
To make the sandwich, toast slices white bread, and butter them on one side generously. Smear the bread with the Bombay sandwich spread, or a combo of coriander and green chile chutney (or any other chutneys you have around). Add generous amounts of raw diced white onion, slices of tomato, sprigs of cilantro and slices of boiled potato (optional). Sprinkle on some chaat masala if you have it.
That's it. If you want to make a more deluxe version, add your choice of mild cheese, and toast in in a panini press, or cook it in a skillet like a grilled cheese.
