This is a classic Appalachian meal. Not especially healthy but cheap, uses up leftovers, and very satisfying! When I was growing up, we would (individually) eat gravy bread several times a week -- as a result, we never had any leftover gravy to feed to the dogs. It was also the reason that we never had any bread heels that went to waste. If you've never tried this, then I'd say that you're in for a special treat, especially if you're a "meat and potatoes" type of person. Enjoy! big pat.
