Prepare the Cucumbers: Begin by thoroughly washing the cucumbers under cool water. For a smoother texture, consider peeling them, then slice the cucumbers into thin rounds using a mandoline slicer or a sharp knife.
Mix the Vegetables: In a large mixing bowl, combine the thinly sliced cucumbers, shredded carrots, sliced red bell pepper, and chopped green onions. Gently toss the ingredients to ensure they're evenly distributed.
Make the Dressing: In a separate small bowl, whisk together the rice vinegar, soy sauce, sesame oil, and grated ginger. If you enjoy some heat, add the chili paste at this stage. Taste the dressing and adjust seasoning by adding salt as needed.
Combine and Toss: Pour the prepared dressing over the mixed salad ingredients in the larger bowl. Carefully toss everything together until each piece is coated with the flavorful dressing.
Add the Finishing Touch: Sprinkle the sesame seeds over the top of the salad and give it one last gentle toss to incorporate the seeds without breaking the vegetables.
Let it Rest: Allow the salad to sit for about 10-15 minutes before serving. This resting period will enhance the flavor fusion and allow the cucumbers to retain their crunch.
Serve and Garnish: Serve the salad in individual bowls for a personal touch or arrange it on a large platter. Garnish with fresh cilantro leaves for an aromatic finish.
