Trim fat off around pork loin if desired.

Combine seasoning salt (if you are reducing your salt intake, use only 1 tablespoon), garlic powder, Italian seasoning, mustard, onion powder and pepper. Rub all over pork loin.

Place pork loin in 4-6 quart slow cooker and add apple juice. Cover and cook on low for 8 hours (or high for 4 hours).

Shred pork or remove from slow cooker and cool for 15-20 minutes to slice.

Optional: add barbecue sauce or other sauces and serve as desired.
