Lightened Slow-Cooker Pork Tenderloin with Onions
  1. 1

    Place the pork tenderloin in a slow cooker with the sliced onions. Pour the wine, water, and soy sauce over the top, then turn the pork to coat. Spread the garlic over the pork, keeping as much on top as possible. Sprinkle with pepper. Cover and cook on Low until the pork is slightly pink in the center, about 4 hours. An instant-read thermometer inserted into the center should register at least 145 degrees F (63 degrees C).
