Tangy Pork and Sweet Potatoes

I have to be honest; I did not taste this. I did, however, cook it and the people in the household attested to it's goodness. Here is the recipe:

TANGY PORK AND SWEET POTATOES

SERVES 4
1 1/2 pounds boneless pork, cut into 1-inch cubes
4 medium sweet potatoes, peeled and cubed
1 large onion, cut into wedges
2 cups hickory flavored barbecue sauce, divided use
1 1/2 teaspoons dried mustard
2 garlic cloves, minced

Place pork in a 3 1/2-quart slow cooker. Top with sweet potatoes and onion.

Combine 1 cup barbecue sauce, dried mustard and garlic in a cup; mix well and pour into slow cooker. Cover and cook on low for 6 1/2-7 hours, or until pork and potatoes are very tender.

When ready to serve, stir in another 1 cup barbecue sauce. Have a fresh green salad and some crusty bread on the side.
