Ummmmmm. wow, I've been cutting my pork chops from loin for as long as I can remember. It is a very versatile meat. Quite under rated as a matter of fact.
Shhhh. Don't tell anyone else or I will end up paying 4.95 a pound for them in a month.
We use them at the store to make stuffed pork chops. Slice them an inch or so thick but butterfly them and bake semi open with a nice sausage stuffing mix. Lay that on a bed of rice and put your favorite vegie side next to it and you have quite a meal.
I have done many a prok chop dinner using loins.
