I'd never heard of it. Sounded like something good to eat, though...and something regional, something else I'm fond of.
Kansas City claims to be where the dish was invented. A quick look didn't have anything about the dish's origins, but there are a lot of places in the Kansas City area that serves it, including one that we have here in northeast Illinois (and, pretty-much everywhere), Olive Garden.
Looks like a trip to the local O.G. is in the near future.
Other places in KC: Garozzo's (4 locations), Cupini's, V's Italian Ristorante, Salvatores, Riccos and Perzelli's. Beginning to sound a bit on the Italian side to me.
One source says you can buy it at a mom-and-pop Italian ristorante or Olive Garden.
It consists of lean meat skewered over an open flame, breaded kabobs served in a puddle of olive oil often on something else.
There are many recipes.
There is also a dish in New York state called spiedie that looks similar.
