Ingredients
2 tablespoons soy sauce
1 tablespoon dry sherry
1 teaspoon hoisin sauce
1/2 pound boneless lean pork shredded
4 dried black mushrooms
2 cups finely shredded Napa cabbage
1 carrot - julienned
3 scallions slivered
1 cup bean sprouts
3 tablespoons peanut oil
2 Eggs - slightly beaten
3 cloves garlic minced
3 teaspoons freshly grated ginger
3 tablespoons chicken stock
2 tablespoons soy sauce
1 tablespoon dry sherry
2 teaspoons sesame oil
1 teaspoon sugar
Hoisin sauce

Instructions
Combine soy sauce, sherry and hoisin sauce in a bowl. Add the pork, toss to coat evenly, cover, refrigerate and marinate for 30 minutes.

Meanwhile, soak the mushrooms in enough hot water to cover for 20 minutes. Drain and thinly slice. Set aside on a plate, along with the cabbage, carrot and scallions.

Heat a wok or large skillet over medium/high heat. Add 1 tablespoon of the peanut oil and swirl to coat. Pour in the eggs, swirling and tilting the wok to form a thin film. Cook just until the eggs are set and feel dry on top, about 1 minute. Transfer to a platter, let cool slightly and cut into 1 inch strips.

Return the wok to high heat, and swirl in the remaining 2 tablespoons oil. Add the garlic, and ginger, and stir-fry to release the aromas, about 1 minute. Add the pork and stirfry until lightly browned, about 2 minutes. Add the reserved mushrooms, cabbage, carrot, bean sprouts, and scallions, along with the chicken stock, and stir-fry another 2 minutes. Stir in soy sauce, sherry, sesame oil, and sugar, and cook, stirring until sauce boils, about 1 minute. Add egg strips and mix well. To serve, spread a small amount of hoisin sauce on a warm Mandarin Pancake or flour tortilla. Spoon about 1/2 cup mu shu mixture in center of pancake, wrap like a burrito, folding the ends to close, and serve.
