I make everything into breadcrumbs. Crackers, biscuits, bread, its all the same, and its all yummy. I even know of people who use cereal thats gone stale as bread crumbs. Since I don't eat cereal, thats not a problem for me.
Just cut or crumble them to the size you want, and bake em for a bit. I usually do my breadcrumbs with olive oil and salt and pper, but its not necessary. Then freeze them if you won't use them right away. Works well.
