Ingredients:

• 2-½ pounds Boneless Pork Shoulder
• ½ cups Chopped Onion
• 1 clove Garlic, Minced
• ¼ cups Brown Sugar
• 1 teaspoon Dry Mustard
• ½ teaspoons Salt
• ¼ teaspoons Black Pepper
• 2 cups Ketchup
• ¼ cups Worcestershire Sauce

Cut boneless pork shoulder crosswise into 1/4 inch slices. Partially freezing it will make slicing easier. (I used pork shoulder spare ribs (or something to that effect). They were pre-cut into thick strips which I then cut in half to make fit.)
In the slow cooker, combine pork, onion, garlic, brown sugar, dry mustard, salt, pepper, ketchup, and Worcestershire sauce; mix well and cover. Cook on low, stirring occasionally, for 6 to 8 hours or until the meat is tender.
