Sounds like something I could make:

Slow Cooker Pork Tenderloin
from @ Charles Sims Weight Loss

2 pound Pork Tenderloin
1/4 cup low sodium soy sauce
1 TBS Yellow Mustard
2-3 TBS maple syrup
2 TBS olive oil
2 TBS Diced dried onions
1 1/2 TSP Garlic Salt or Powder

Mix ingredients above. Pour over Tenderloin in the crock pot and cook on low for 6 hours.
