Stir Fried Beans (and maybe bok choy) with Tofu and Chiles

Drain and dry tofu slices on paper towels. In a small bowl or measuring cup combine soy sauce, rice wine or sherry, and stock or water. Combine salt and sugar in another small bowl and cornstarch slurry in another. Have all ingredients within arm’s length of your pan.
Heat a 14-inch flat-bottomed wok or 12-inch steel skillet over high heat until a drop of water evaporates within a second or two when added to the pan. Add 1 tablespoon of the oil to the wok or pan and swirl the pan so that the oil coats the sides, then add tofu and stir-fry until lightly colored, 1 to 2 minutes. Remove to a plate.
Swirl in remaining oil, add garlic, ginger and jalapeno and stir-fry for no more than 10 seconds. Add beans and white parts of the scallions, and stir-fry for 2 minutes. Add salt and sugar, toss together and add soy sauce mixture. Stir-fry for 1 to 2 minutes, until vegetables are crisp-tender. Return tofu to the wok along with scallion greens, cilantro and cornstarch slurry. Stir together just until lightly glazed, and remove from heat. Serve with hot grains or noodles.
