Blistered Green Beans with Coconut, Sesame & Scallion Oil

Combine scallions and ginger in a small heatproof bowl. Heat oil in a large skillet over medium-high heat until shimmering. Carefully spoon 3 tablespoons of the oil into the bowl. Add beans to the remaining oil in the pan and cook, without stirring, until starting to blister, about 2 minutes. Season with salt and pepper; continue to cook, stirring occasionally, until the beans are tender, about 5 minutes more. Serve topped with the scallion-ginger oil, coconut and sesame seeds.
