Heat a wok over high heat, and add 2 tablespoons groundnut oil. Pour in the beaten egg, and scramble, and then set it aside.
For the filling:
Reheat the wok, and add the groundnut oil, followed by the garlic, if using, and ginger. Stir-fry quickly for a few seconds to release the aroma. Cook's Note: If you don't like garlic you can leave it out and add a little extra ginger for taste.
Add the bean sprouts, peppers, and mushrooms, and cook until the vegetables are tender, but still have a bite.
Return the eggs to the wok, and season to taste with the light soy sauce, sesame oil, and white pepper. Cook's Note: You can add some sliced honey-roasted ham at this stage, if you wish. Transfer the dish to a large plate, and garnish with the pickled red cabbage.
To serve: Place the plate in the center of the table alongside the pancakes in the steamer. To eat, fold a pancake in half, and then half again, to give it a fanned, conical shape. Stuff the pancake with the vegetable filling, and eat it immediately!
