Wait until the bread is stale then break it into large chunks and put it into the food processor.
Process on high until all is crumbs.
Use immediately or store in a zipper bag in the freezer.
You can season them with Italian seasoning if you like.
Use them for this http://hearthandhospitality.blogspot.com/2011/08/parmesan-chicken-nuggets-for-picky.html or what ever you want. I like having them in the freezer all ready when I need them and nothing wasted.
