"1 cup seasoned bread crumbs"
Kind of ambiguous, the "seasoned" can have many interpretations...
(Ping myself. I'll find my "local" recipe soon...)
I use extra stuffing mix or croutons for bread crumbs, putting them in a ziplock and pounding and rolling with a rolling pin.
Some prepared bread crumbs are already seasoned that you buy in the store. Most have Italian seasonings though. I would use plain unseasoned and then add your own seasonings and herbs.
This is making me hungry :)
