They can also be put in microwaves. Hmm, I always assumed that this food would be widely known, since it is over here in the Netherlands... I'd love to put a lot of animal free 'kroepoek' links over here, but they would probably only be selled over here, so there's not much use. Conimex is a large brand over here, but the english site only shows the prawn crackers, not the vegetarian ones. I would suggest going to asian marktets, though. They have lots of varieties, and making them yourself is lots of fun, like other said.
