Trim and halve cucumber lengthwise; cut crosswise into ½-inch-thick half-moons. Trim and thinly slice scallions, separating whites from greens. Peel and mince or grate ginger. Peel and mince or grate garlic.
In a medium bowl, combine cucumber, scallion greens, vinegar, sesame seeds, ½ tsp sugar (1 tsp for 4 servings), and a big pinch of salt. Set aside, stirring occasionally, until ready to serve.
