Cooked mystery meat can be obtained by cooking raw mystery meat or obtained when pickpocketing vyres in Darkmeyer. It heals 5 hp. When eaten, a message will appear in the chatbox: "It heals some health, and tastes concerningly nice."
The mystery meat can be given to Frank, the little Bloodveld roaming Darkmeyer. Doing so gives the message "You let the bloodveld eat the mystery meat. He seems to enjoy it quite a lot."
Based on the examine text and the message when eaten, it is likely that mystery meat is in fact human meat.
