MIX broth, soy, lemon juice, oil, garlic powder, ginger and pepper in a shallow plastic covered container*. Add pork and turn to coat. Cover and refrigerate 5 hours or overnight, turning occasionally.
REMOVE pork from marinade and discard marinade. Place pork in baking pan and bake at 350°F. for 25 min or until fork tender.
*I marinate in a re-sealable plastic storage bag for convenience.
