Thinly slice the cucumbers into 1/8-inch rounds and thinly slice the green onions, keeping them separate. Finely grate the fresh ginger and roughly chop the peanuts. Having everything prepped and ready ensures the salad comes together quickly and the vegetables stay crisp.
In a small bowl, whisk together the rice vinegar, honey, sesame oil, chili garlic sauce, salt, and freshly grated ginger until well combined and the honey is fully dissolved. Taste and adjust seasonings as needed—I like to add an extra pinch of salt if the vinegar seems too sharp, as it balances the acidity beautifully.
In a large bowl, combine the sliced cucumbers and green onions. Pour the dressing from Step 2 over the vegetables and toss gently but thoroughly, making sure every slice is coated with the flavorful liquid. The salad can be served immediately for maximum crunch, or chilled for up to 2 hours if you prefer softer cucumbers.
Transfer the salad to a serving dish and top with the toasted sesame seeds and roughly chopped peanuts just before serving. I always add the nuts at the last moment to preserve their crunch—they'll soften quickly once they absorb the dressing.
