1lbpork tenderloin, sliced thinly (vegetarian/vegan: use tofu following directions from Kung Pao Chicken recipe at https://www.daringgourmet.com/2013/01/08/30/)
1lbthick round Chinese egg noodles (can substitute Japanese udon noodles), cooked according to package instructions (fresh noodles are even better, in which case cut the sauce in half because the fresh noodles weigh more) (vegans: use wheat noodles)
To make the marinade, combine the soy sauce, oyster sauce, sugar and ginger and stir until the sugar is dissolved. Place the pork in the marinade and let sit for 10 minutes. Drain and reserve the marinade for later.
Heat the oil in a wok or heavy skillet on high heat and fry the pork for one minute or until done. Remove the pork and set aside. Next fry the white parts of the cabbage and green onions along with the garlic for 30 seconds or until tender. Return the pork to the pan along with the reserved marinade, the sesame oil, chicken/cornstarch mixture and the green parts of the cabbage and green onions. Cook for 30 seconds. Add the noodles and stir until combined. Add white pepper to taste. Serve immediately.
Notes
The saltiness of the soy sauce varies from brand to brand. Start with a 1/3 cup and add more as desired.
