Notes
TIPS:
When slicing the pork tenderloin to stuff it, place an object such as a wooden spoon on each side to stop the knife from cutting all of the way through the pork to the cutting board.
Pork tenderloin cooks quickly, and may not be brown when it has finished cooking. To achieve a browned look, change your oven setting to broil during the last few minutes of cooking.
