There's no need to purchase breadcrumbs for any recipe. They are easy to make, even at the last minute.

Take 2 loaves of your favorite bread.

Either cut into slices or ask baker to cut into sandwich loaf. Spread both loaves on a cookie sheet and put into oven for 24 hours minimum. The ambient heat of your kitchen space will dry out the slices to stale and stiff. Break up the slices into a storage container and voila, you have bread crumbs. If you know you want a particular spice (for example, sage for stuffing/dressing, add dried sage leaves chopped into the bread crumbs) add while crushing the stale bread so as to work the spice thoroughly through the mix.
