Is Burger King looking at a new-day sloppy joe?

Call it the Great Sandwich Mystery.

A now-deleted posting on a consumer advocates’ website described what its anonymous author said was an unusual sloppy joe-based sandwich under consideration by Burger King.

The item featured a patty formed from sloppy joes, the chili-like mix of ground beef and sauce that’s typically served in a somewhat soupy state on a roll. The round of compressed sloppy joes depicted on Consumerist.com was breaded and deep-fried, according to the post. Its anonymous author said he learned of the test product, and pinched a photo, while participating in a survey conducted by BK.

But the posting was quickly yanked by TheConsumerist, a website run by the same company that publishes Consumer Reports. No reason was given.

The item was apparently on the site long enough for others to re-blog some of the information. IckyPeople.com even got the photo, which you can see here.

Webizens have given the purported BK product a host of names, including The WTF and, in IckyPeople’s case, the Vomit Burger.
