Not like out of a box - these are mostly the places that do homemade croutons. Which starts with bread. So basically it just means breaking up the bread instead of leaving it all one piece... I've also heard the whole big piece referred to as a crouton, now that I think of it.

It totally depends on the place though. Speaking of which, I need to start keeping notes on which places do it well, and which not. There's one restaurant I go to regularly that doesn't do it very well, but I keep ordering it because I keep forgetting which one it is that I don't like.
