Thinly slice the cucumbers into rounds or half-moons using a sharp knife or mandoline for even, delicate pieces.
Place the sliced cucumbers into a large mixing bowl and set aside.
In a small bowl, whisk together grated ginger, lime juice, soy sauce, honey, sesame oil, and vegetable oil until the dressing is well combined and slightly emulsified.
Pour the dressing over the sliced cucumbers, then toss gently to coat all the pieces evenly.
Let the salad sit for about 5 minutes, allowing the flavors to meld and the cucumbers to release some water.
Sprinkle toasted sesame seeds and sliced scallions over the top for added crunch and freshness.
Give the salad a final gentle toss, then it's ready to serve as a crisp, refreshing side dish.
