AFAIK until plastic was invented all sausages were made from intestines ... so were condoms and some other items.
So far I've seen ...
a) a "yugoslav" grill restaurant near where I live (the world's best burgers, raznjici, cevapcici, and hmmm ... gurmanska pleskavica, basically a burger patty stuffed with ham and cheese); they have "grilled intestine" on the menu, but I was too much of a coward to try that.
(And too focused on liver wrapped in pork net (pig's caul ... another versatile, tasty item that many people seem to hate because it's yucky.)
b) sweetbread a.k.a calf thymus ... a delicacy here, but becoming rare; dog's food in most other countries.
c) Apparently there are several recipes for "cut up inner organs, stuff into stomach or intestine, heat until done". The Scots call it haggis and boil it; Austrians call it sausage and smoke it; apparently in Greece there's an appetizer from "cut liver and stuff in intestine, grilled" ... :-)
d) A fairly widespread food is made by insects who collect small bits of flowers, add their bodily fluids to it, and then store it ... 'honey'. (Oh well. Most Euros shiver when you tell them about eating what seems to be a rotten egg, namely the chinese 100-year-egg; most Chinese seem to hate the very idea of eating a brick of rancid cow's milk infested with mold (a.k.a. blue cheese), so I guess we shouldn't judge the dwarves for eating maggot cheese.
About the inspiration for dwarven cheese ... whenever I think of the concept, I don't know whether to gag, feel aroused, or giggle like a maniac. Imagine a pretty dwarven girl vigorously milking a foot-long, wriggling maggot until it squirts a milk-like substance. Ugh. Or mmmmmhm? Or is that just my perverted imagination?
Now I'm still curious as to what grilled intestine tastes like. I'm thinking mildly meat-flavor chewing gum?
PS Also had dove/pigeon once. At a press conference for Prince of Persia, where they'd hired some Persian caterer. Unfortunately the breast I got was only half-cooked; I mean "pink" is okay, but "dripping blood" is something I prefer a beef steak to have, not fowl. Still tasted good - darkish meat, closer to duck than to chicken, and very tender.
