Heat peanut oil in a large wok over high heat. Add ginger, scallions, cabbage, carrots, and mushrooms; cook, stirring and tossing constantly, until vegetables are wilted, about 5 minutes. Add pork and marinade and 6 tablespoons water; cook, stirring constantly, until pork is cooked through, 4 to 5 minutes. Serve immediately wrapped curry pancakes, with the plum sauce on the side.
Curry pancakes make the best wrappers for this, but six-inch flour tortillas can also be used.
