uses for breadcrumbs?

[psocoptera]

I bought a bag of breadcrumbs from my grocery's bakery to make chicken dumplings. The dumplings were great but I have most of the bag of breadcrumbs left. They were cheap so what I don't want is something to do with them that involves buying much more expensive ingredients - for instance, I'm sure I could use them to bread some chicken breasts, but then I'd be buying chicken breasts. What I do want is something to do with them using mostly ingredients that I have around anyways such as eggs and milk. Can they for example be turned back into some sort of bread, muffin, or biscuit?
