Slow cooker Pork Tenderloin with Pineapple

Ingredients 
1  small to medium pork tenderloin
1/2  teaspoon salt
1 teaspoon ground black pepper
2 T. Lite Soy Sauce
2 cups chopped mushrooms (optional)
1 (20 ounce) can pineapple chunks, undrained
1 cup chicken broth 
1 small onion, chopped
1-2 cloves chopped garlic 

Directions

1. Rub the pork roast on all sides with salt and pepper, and place in a slow cooker. Pour in the pineapple chunks and juice, and add remains ingredients. Cover, and cook  6-7 hours on Low. I served this with brown rice and spinach because I had leftovers but these can easily be made paleo or low GI by serving over salad, veggies or sweet potato.
