Whenever I have leftover bread-end pieces, sliced bread, or rolls not eaten at dinner parties-I throw them into a zip-top bag in my freezer. Then when I need breadcrumbs, I slightly thaw a few pieces and grate them on a box grater (for small amounts) or in my food processor (for larger batches). The partially frozen bread transforms easily into fine crumbs. This way bread never goes to waste, and I can always have fresh bread crumbs in a matter of minutes.
