Start by washing the cucumbers and jalapeños under cool water. Thinly slice the cucumbers and jalapeños, adjusting the number of jalapeños based on your taste.

In a mixing bowl, combine the sliced cucumbers, jalapeños, chopped green onions, and sesame seeds. Toss gently.

In a separate bowl, whisk together rice vinegar, soy sauce, sugar, sesame oil, and salt until well blended.

Pour the dressing over the cucumber mixture and toss gently until all ingredients are coated.

Cover and refrigerate for at least 20 minutes to allow flavors to meld.

After chilling, taste for seasoning and adjust as needed. Serve garnished with sesame seeds and jalapeño slices.
