Sloppy Joes and Sloppy Janes

I recently explained to somebody what a sloppy joe was. I wondered about its history, so I visited Wikipedia:

According to the “In Mama’s Kitchen” website: “[R]esearch at the Carnegie Library suggests that the Sloppy Joe began in a Sioux City, Iowa, cafe as a “loose meat sandwich” in 1930, the creation of a cook named Joe…”

Well, that clears things up. Sort of. Here’s a variation of the term:

A ‘feminine’ counterpart named Sloppy Jane sandwich consists of hot dog sausage, baked beans, mustard, minced onion, chili sauce, packed into hot dog buns.

This sloppy jane business is news to me.
