RE: How do you cook your tenderloin?
Personally I'd rather have them cooked in an iron skillet than on the grill.
I just get some canola oil real hot and drop the butterflied chops in the skillet. Let them cook until they're as you like them and serve. (The more rare they are...the more tender they will be)
Because the chops have no fat in them, they are to be cooked REALLY FAST and HOT. That is the key.
