Using a fork, lightly score the surface of the cucumbers lengthwise—this optional step allows the dressing to better adhere.
Slice the cucumbers into thin rounds and transfer them to a mixing bowl. Sprinkle with salt and let them rest for approximately 10–15 minutes to extract excess water.
Drain the released liquid using a fine mesh strainer, ensuring the cucumbers remain undisturbed by rinsing. Place them in a clean bowl.
Incorporate the scallions, ginger, garlic, rice vinegar, soy sauce, sesame oil, sweetener of choice, chili garlic sauce (if using), and toasted sesame seeds. Toss thoroughly to evenly distribute the flavors.
Taste and adjust seasoning, adding more chili paste for extra heat or sweetener for balance, if desired.
Refrigerate until ready to serve. While best enjoyed the same day, this salad can be stored in an airtight container in the refrigerator for up to three days.
