One of the pains of pork tenderloin is removing the "silverskin" connective tissue. I was in Walmart and picked up a pack of Prairie Fresh Natural Pork Tenderloin. Had never bought the brand before but it was the only un-seasoned brand they had. When I opened it up, I was pleasantly surprised. Virtually no silverskin-only about a 1 inch section on one end of one of the pieces. The other had none. I am impressed with the trimming and it saved me a bit of time.
