I don't know where to begin. This is positively horrifying! So much death and fat mingling, rotting inside rot inside rot; an animal shoved up another animal shoved up yet another animal. It's necrophilic, full-body rape to the third power. You should serve time in the hole for even considering this monstrosity.
Seeing as how this was obviously inspired by those Russian doll sets, I'd like to add Russian dolls to our list of things not to eat.
Recommended alternative: Stuffed tomatoes ...if you absolutely have to stuff something.
