If you have a recipe that calls for bread crumbs, make sure they're clean by making your own the easy way. Make a big batch and freeze for up to 6 months!
Toast your bread. Make sure it's well toasted, even if you have to toast it twice. Then, let it sit out for a few minutes to cool completely. You want the bread to be dry, dry, dry.
Break up the bread so you can get it into a processor and add all your other ingredients as well.
Blend until you have a relatively fine mixture, and you're done!
