Just out of curiousity, are you really going to be able to pack that many granola bars? How much luggage are you bringing?
Another point: are you staying with family or people you know, or you going on some kind of service trip? If it's the former, you may be able to swing this, but please bear in mind that your hosts might be way insulted at your bringing your own food. Culturally, they may not understand vegetarianism the way Westerners do.
I know you just asked one question and I'm sorry if it's rude of me to offer unsolicited advice like this, but please consider these things if you haven't already.
