Place on 3" rack in NuWave oven. Set the cook time for 12 minutes and start the oven. After the NuWave times out turn the tenderloins over and set it for another 12 minutes. When it times out again insert a meat thermometer. It should read about 145 deg. If not put it back on for another couple of minutes. When done let it rest for at least 15 minute.
