Preheat oven to 325 degrees. Cover pork with foil and heat for 20-30 minutes or until reaching an internal temperature of 165 degrees. If you like your pork with sauce, brush on your Mac’s sauce of choice before heating. To retain the original flavor and moisture, do not overheat. Cooking times and temperatures can vary from oven to oven. A meat thermometer should read 165 degrees when fully reheated.
