In a small bowl, combine the marinade ingredients.
Trim the silvery skin from the tenderloin. Place in a seal-able container or in a zip-top bag. Pour marinade over the pork and seal. Marinate at least 30 minutes or overnight, if possible.
Preheat oven to 425 degrees F.
Heat a tablespoon of olive oil in a large cast iron (or other large, oven-safe skillet). Sear the tenderloins on each side; about 2 minutes per side; and slide the skillet into the preheated oven.
Bake uncovered for about 18 minutes, or until the meat registers 145-160 degrees F on a meat thermometer. Remove from the oven and tent with foil. Rest for 5-10 minutes to allow juices to redistribute. Slice into ½-inch medallions and serve immediately.
