If you're like me, you throw away a lot of bread. I even freeze it only to throw it out later anyway. So I decided to make breadcrumbs. I'm not sure if white bread would work well (since it's so soft) unless you left the bag open for a day or two to let it dry out a bit.
Day old bread (I used 3 whole wheat flat breads from my freezer, defrosted)
Preheat the oven to 400F.
Put the bread in a food processor (but don't over fill it) and pulse until crumbly. There will be larger chunks but don't worry at this point.
Place in a thin layer of crumbs on a baking sheet (or two) and bake stirring as it browns. Bake until it gets crispy but not burnt. I didn't time it. Oops!
Remove from oven and allow to cool completely. Take the crumbs for another ride in the food processor to make them as fine or course as you like. Season with herbs, spices or parmesan cheese if desired.
I left mine plain and stored them in the freezer.
