Leviticus 3. This chapter sure is a doozy. God tells the Israelites that all peace offerings made to him must be without blemish. Any part of the animal that is not burned on the altar must be eaten by the priests. Also, don't forget the salt. Oh, and God also demands that the offerer put his hands on the animal's head before it is killed. A little messed up, but hey, that's God for ya.
