Just loaded it up to check. on the spit there are Roasted Dwarf Ribs, Roasted Dwarf Belly, and Roasted Dwarf Leg. They don't provide any camp supplies, weigh 0.5, and have a value of 1gp. The descriptions are pretty gruesome, including mention of a belly button. Interestingly, their names don't show up on the screen when you hold ALT, which may be why some people missed them.
