But yes, that being said, a lot of men from the region won't/can't cook. And many are picky about what they would even consider to be Indian/Pakistani food - someone from Kerala isn't necesarily going to like something from Delhi. Kind of like BBQ in this country (although I know I guy from Goa who makes an incredible beef brisket).
I'm surprised one of their fellow migrants hasn't thought of setting up a kitchen at the work sites or living quarters there - it's got to be more cost effective than flying it in.
If they found a wife who could cook, maybe they wouldn’t be bachelors anymore eating shipped home cooked meals no more no more.
