Start by rinsing the cucumbers under cool running water to remove any dirt. Using a sharp knife, slice the cucumbers at an angle to create beautiful oval-shaped pieces, aiming for about ¼-inch thickness.

Place the cucumber slices in a large mixing bowl and sprinkle with salt. Gently toss to ensure they're evenly coated, and let them sit for 10 minutes.

Transfer the salted cucumber slices to the refrigerator for at least 20 minutes to chill. After chilling, drain any excess water that has accumulated.

In the same mixing bowl, add sesame oil, light soy sauce, sugar, rice vinegar, and chili oil. Whisk together until well combined.

Add the drained cucumber slices back into the dressing mixture, tossing gently to coat each slice evenly. Sprinkle with sesame seeds before serving.
