Prepare Carolina Sauce; set aside. Preheat oven to 350 degrees F.
Trim the tenderloin of fat and silverskin. Note: Silverskin is a silvery-white connective tissue. It does not dissolve when the tenderloin is cooked, so it needs to be trimmed away. If the silverskin is not trimmed off, it will cause the tenderloin to curl up into the shape of a quarter moon. Pat the roast dry with paper towels.
Cut pork tenderloin lengthwise into eight 1/4-inch slices (slices should be just a little larger than the shape of the bacon - trim if necessary). Note: If you partially freeze the uncooked pork tenderloin, it is easier to cut into slices.
Place a slice of bacon on top of each pork slice. Starting at one end, roll up pork/bacon into a spiral; secure with 2 to 3 wooden toothpicks. Brush the prepared Carolina Sauce over each of the pinwheels; reserving remaining sauce.
In a pie plate, combine pecans, salt, and pepper. Roll each pinwheel in the pecan mixture to coat.
Place pinwheels onto a rack in a shallow baking pan. Bake, uncovered, approximately 30 minutes or until a meat thermometer inserted into thickest part of the roast registers 155 degrees F.
This is the type of cooking and meat thermometer that I prefer and use in my cooking. I get many readers asking what cooking/meat thermometer that I prefer and use in my cooking and baking. I, personally, use the Thermapen Thermometer shown in the photo on the right. To learn more about this excellent thermometer and to also purchase one (if you desire), just click on the underlined: Thermapen Thermometer.
Remove from oven and transfer onto a cutting board; let pinwheels stand 10 to 15 minutes before serving (meat temperature will rise 5 to 10 degrees after it is removed from the oven). Transfer onto a serving platter and drizzle with Carolina Sauce over the pinwheels.
Makes 4 servings of 2 pinwheel each.
