Preheat oven to 475°F.
In a small bowl, toss beans in ½ tbsp oil. Transfer to a baking sheet. Spread out in a single layer and roast for 5 to 10 minutes, until crisp-tender.
Place ginger, scallions, mustard greens and garlic in a wok and quickly stir-fry on medium-high heat for 20 seconds. Add beans and the remaining ½ tsp oil and toss well. Season with sugar and salt and sauté for another 25 seconds. Remove from heat and stir-fry for 5 seconds. Add a splash of wine (or sherry) and toss again.
Transfer to a serving plate and serve immediately.
