Step 1

Combine rice wine (or sherry), soy sauce and sesame oil in a small bowl. Combine salt and sugar in another small bowl.

Step 2

Heat a 14-inch flat-bottomed wok over high heat until a bead of water vaporizes within 1 to 2 seconds of contact. Swirl in 2 teaspoons peanut (or canola) oil. Add ginger and jalapeno and stir-fry until fragrant, about 10 seconds. Add carrot and stir-fry 1 minute. Swirl in the remaining 1 tablespoon peanut (or canola) oil, bell pepper and corn, sprinkle on the salt mixture and stir-fry until the vegetables are almost crisp-tender, about 2 minutes. Add lettuce, swirl in the rice wine mixture and stir-fry until the lettuce is just limp, about 30 seconds.
