Marinate beef in standard (all-purpose) marinade for at least 15 minutes. heat wok. Add just enough peanut oil to stir fry the vegetables. Drop in the begetables. (I add the green vegetable first and stir fry it for 10-20 seconds before adding the onion, because I like my onion crispy and crunchy, and it takes less time to cook than bell pepper or broccoli or bean sprouts.) Stir fry until 3/4 done. Remove vegetables, set aside, keep warm. Wipe out the wok. Reheat it until very hot. Add about 1-2 Tbsp of peanut oil. Add garlic (and ginger if desired). Stir fry for about 10 seconds. Add meat and stir fry for about 60 seconds. Put the vegetables back in, add the soy sauce and wine. Stir the cornstarch mixture up to recombine it, and add. Continue to lift, toss, stir, etc. until the sauce is thickened and translucent. Just before serving, add a few splashes of sesame oil. Serve with plain rice.
