Not your dinner, their dinner. If you're gonna be a cannibal, at least be a classy one. Buy them a nice Chianti or something.
If you can find a magic mirror pond, you could copy yourself then eat them/you. Victimless crime. Totally not going to result in deep emotional trauma.
I wouldn't recommend it. It would likely have unfortunate results. It also wouldn't be cannibalism, now would it? I could probably copy you if you want.
If you count horse as a pony, then maybe. Ok, lets do this. *puts on lab coat, conjures up phonebox looking thing* Get in.
