BreadCrumbs???
You put Bread (which you can cook yourself) in the Grain Mill. There doesn't seem to be anyway to buy Bread Crumbs and no one seems to give Bread Crumbs as a reward for doing their request. So I think that is the only way. I'm not totally sure though.

If you want the Bread Crumbs to make Cream Croquettes for Dirk try checking Howard's shop during Spring. He will sometimes sell Cream Croquettes.
