Hey, you can grill anything that's grillable!!!
and you can deep fry things that aren't even edible.. deep fried twinkies for instance. lol
btw. all sausage can be cooked again although i don't think i have ever seen krakowska or the like heated.
the white sausage has to be cooked though. it is raw at the store. personally i love it in white borscht.
besides that all others can be eaten as they are.. even kiszka.
