Lunch for your kids: Indian or not?

Many Indian parents raising kids outside of India wonder every day if their kids should be taking Indian lunch - which may look and smell exotic to their friends - or should they pack them more acceptable - and familiar - lunch? This is a micro level question of a macro level issue. Should you make them feel proud of their Indian heritage or should you teach them to assimilate?

Are you a parent facing this dilemma? What do yo think?
