Green beans are fried until wrinkled and blistered, then tossed with garlic, preserved vegetables, and minced pork. This family-favorite Sichuan dish is packed with flavor and provides a good source of protein and fiber.
Trim the green beans and dry thoroughly to ensure good blistering.
Heat 4 tbsp of vegetable oil in a wok over medium-high heat. Add green beans and stir-fry them, turning occasionally, until the skins are wrinkled and blistered, about 7–10 minutes; remove beans and set aside.
Pour off excess oil, leaving about 2 tbsp in the wok. Lower heat to medium, add the minced pork and stir-fry until fully cooked and lightly browned, breaking up lumps.
Add chopped garlic, preserved mustard greens, and the white part of scallions. Stir-fry for 1 minute until fragrant.
Return green beans to the wok. Season with soy sauce, Shaoxing wine, sugar, and sesame oil. Stir-fry briskly over high heat for 2 more minutes, ensuring beans are well-coated and heated through. Garnish with scallion greens and serve hot.
