There's not a preservative free topic per se, but many of the recipes posted are indeed that way. And most of the others could be easily turned into one with little effort.
Just pick a forum topic and dig through the posts. You'll find some pretty amazing stuff in here. And if you find something you'd like to try but the way it's posted doesn't work for you, ask for help with what may work in it's place. You'll not find a more eager to help bunch anywhere.
I cook almost exactly like Norg does. =P I just leave out the meat too.
