Foods To Carry While Travelling In Train For 3 Days

You can carry curd rice, ajvayin pooris with extra moin (oil that you add while making the dough), bittergourd fry, or stuffed bittergourd without onion, theplas with pickle, plain bread and butter sandwiches with some namkeen or mixture. You can take apples, oranges and buy bananas on some station.
Idlies coated with sesame oil and podi has a longer shelf life than normal idli.
For the first day you could take some chapatis with any curry you make without adding water. You could put some milk and oil while kneading the chapati dough so that they last longer. Or you could make some mixed vegetable rice with extra oil. Hope it suffices.

Have a happy journey and enjoy
