Let you in on a dirty little secret.
Pork tenderloin sammies ain't tenderloin.
It's pork steak( shoulder) that's ran through the tenderizer.
Honestly its better than tenderloin.
Without the bone and fat, what's tenderloin have to offer?
It gets dry fast, and not much taste.
Pork shoulder on the other hand has fat in it.
And is a tastier muscle.
Tenderizer it, and you have a superior piece of meat. Cheaper.
