GINGER-SCALLION CHICKEN

Steps:

• Cut the scallions in quarters lengthwise, then cut crosswise into 1 1/2-inch-long pieces. You should end up with thin blades of scallions. Separate out the dark green tops from the pale green and white parts. (You don't have to be very thorough; some mixing of colors is fine.)
• Heat oil in a wok or 12-inch skillet over very high heat. When it's shimmering but not smoking, stir in chicken and salt. Cook, stirring almost constantly, until chicken is barely cooked and no longer pink, 3 to 5 minutes. Use a slotted spoon to transfer chicken onto a serving plate, leaving the oil in the pan. Immediately scatter cilantro and scallion greens (not whites) over hot chicken.
• Return wok to medium-high heat. Make sure there are at least 2 tablespoons oil in the wok. If not, add more oil. Stir in ginger and cook until lightly browned, about 1 minute. Stir in scallion whites, soy sauce and sugar, and cook for another 30 seconds (if using a skillet, remove from heat). Immediately spoon the contents of the pan evenly over chicken and herbs. Serve right away.
