Whither Hobo Meatloaf?

Can anything be "hobo-ized"? Burgers are hobo-ized by replacing the beef patty with thick-cut bologna. Can the same be done for other foods? I think meatloaf may be an extreme example, but it definitely gives you something to think about. And does hobo-ization automatically mean that only bologna is substituted? Are there other meats out there that are Hobo Kosher?
