1. In small bowl, stir together soy sauce, sherry, sugar, cornstarch, white pepper, pepper flakes, mustard, and water until sugar dissolves; set aside.

2. Heat oil in 12-inch nonstick skillet over high heat until just smoking. Add beans and cook, stirring frequently, until crisp-tender and skins are shriveled and blackened in spots, 5 to 8 minutes (reduce heat to medium-high if beans darken too quickly). Transfer beans to large plate.

3. Reduce heat to medium-high and add pork to now-empty skillet. Cook, breaking pork into small pieces, until no pink remains, about 2 minutes. Add garlic and ginger; cook, stirring constantly, until fragrant, 15 to 20 seconds. Stir sauce to recombine and return beans to pan with sauce. Toss and cook until sauce is thickened, 5 to 10 seconds. Remove pan from heat and stir in scallions and sesame oil. Serve immediately.
