I'm taking a group on a Grand Canyon rim-to-rim and discover that one of the participants is a dedicated vegetarian. I believe there are vegetarian foods out there but I have no idea which (if any) are any good -- as I'm not vegetarian and have never had to deal with the issue before.

Anyone out there with an opinion about meeting the needs of this person?
I don't think home dehydration will be an option, here. Pretty much will need dried or freeze-dried that is commercially available.

Thanks in advance.
