Yep that's the origin of the word. Traditional Spiedies don't have any veggies at all. Originally lamb, over the years it's become pretty standard to use lamb, pork, chicken, beef, venison, I have even had fish.
On a skewer, and on french bread, or some other crusty bread. That's it. No sauce, no other condiments, just the meat marinaded grilled and on bread.
