One of the pitfalls of making your own bread is that it goes stale pretty quickly - usually within about 2-3 days. Alas! My heart distresses over waste! (Yes, I'm embellishing a bit :) Anyway, when my bread is going stale, I just go ahead a replace it with a fresh loaf and slice up whatever is left of the stale and put it in the freezer in a big (gallon or 2 gallon) size ziploc bag. You see stale bread is perfect for french toast or bread puddings or those casseroles that require stale bread. I personally love to use my stale bread for french toast in order to create my favorite concoction ever - the Monte Cristo! And with a sandwich like that, you need your bread to hold up a little :)
If you want to know what to do with the bread loaf heels - buzz them in the food processor and freeze them - you now no long have to purchase bread crumbs!!!
