Stuffed Cuban Pork Tenderloin

Heat oven to 350°F. Line 15x10x1-inch pan with cooking parchment paper. Insert knife one-third of way up from bottom of tenderloin along 1 long side, and cut horizontally, stopping 1/2 inch before edge. Open up flap.

Keeping knife parallel to cutting board, cut through thicker portion of tenderloin about 1/2 inch from bottom of tenderloin, keeping knife level with first cut and stopping about 1/2 inch before edge. Open up this flap.

Press sides of tenderloin down so it lies flat. Cover with plastic wrap; pound with flat side of meat mallet to 1/2 inch thick. Spread mustard down center of tenderloin. Top with cheese slices, pickle relish and ham slices, folding to fit, if necessary.

Tightly roll up tenderloin lengthwise, and tie tightly with twine. Brush tenderloin with oil, and sprinkle with salt and pepper.

Heat 12-inch nonstick skillet over medium-high heat. Add tenderloin; cook 5 to 6 minutes or until browned on all sides. Transfer to pan; roast 28 to 32 minutes or to at least 145°F. Remove from oven; tent with foil and let stand 3 minutes.

Remove strings from pork; cut into 1/2-inch slices. Serve with extra mustard, if desired.
