I left the crouton hint before, but recently I had some leftover Pillsbury breadsticks.  We seasoned them before baking with garlic powder and Italian seasonings, just to serve with dinner so they were a little bit seasoned.  I cut them into rounds and toasted them.  They made fantastic croutons!  They were so tasty, I may even use them to make a batch of croutons.  But if you happened to have only a few left over you could slice, toast it up and keep it in an airtight container for later use.
