Cut pork into strips, 2"x1"x1". Chop scallion finely.
In a small dish, mix together the ginger, Hoisin sauce, sherry, scallion, and garlic. Add the pork strips, coat with the marinade an leave for 4 to 6 hours, stirring occasionally.
Drain the pork, and rub it with honey. Place on a greased rack in a roasting pan over 1 inch of water. Cook for 25 minutes at 350°F. Slice into thin pieces.
Heat the oil in a saucepan, add the chopped ginger and salt, and stir-fry for 2 minutes. Rinse the bean sprouts in cold running water, drain, and add to the saucepan with 1 Tbsp of water and the sugar. Heat gently, stirring until well mixed.
Add the pork, cover, and heat through.
