I place the breadcrumbs on a parchment covered cookie sheet and sprinkle with a handful of freshly grated Parmesan cheese. I'm sure you could use cheddar or some other hard cheese of your choice.
Now preheat your oven to 395 degrees and bake for about 15 min . Toss them up a bit and back in the oven for about 10 min.If your bread is very dry to begin with you might need to watch the last few minutes a little closer to avoid getting too dark.
When cooled you will have a tasty crouton great for soup or salad or just to nibble on.They keep forever in a storage bag on the pantry shelf.An added benefit is your house will smell like you have been making some really intense cooking but, ..............we all know this will only take a few minutes from start to finish. Now get back to the couch and do a little reading...........or take a nap.............said the hobbit
