Preparation Pour oil into a large high-sided skillet, add garlic, and set over medium heat. Cook, stirring often, until garlic is barely golden, about 2 minutes. Add a third of the greens to skillet and toss to coat with oil and garlic. Cover skillet with a lid and cook until greens are slightly wilted, about 2 minutes. Uncover skillet; add sake and another third of greens and toss to combine. Cover and cook until greens are slightly wilted, about 2 minutes, then add remaining greens. Cover and cook until slightly wilted, about 2 minutes. Remove lid from skillet, add lemon zest to greens, and continue to cook, stirring often, until greens are completely wilted and tender and most of the liquid has evaporated, about 2 minutes. Season with salt. Transfer greens to a serving bowl and top with sesame seeds.
