Start by washing the cucumbers under running water, then slice thinly (⅛-inch thick) and sprinkle with salt. Let drain in a colander for 30 minutes to 1 hour.

While the cucumbers drain, prepare the dressing by whisking together rice vinegar, soy sauce, sesame oil, chili garlic sauce, honey, minced garlic, and grated ginger in a bowl.

In a large mixing bowl, combine drained cucumbers, chopped green onions, sesame seeds, and cilantro (if using). Drizzle the dressing over and toss gently.

Place the salad in the refrigerator for 30 minutes to enhance the flavors. Serve chilled.
