Start by peeling the carrots and slicing them into thin julienne strips using a vegetable peeler or julienne peeler. Place them in a large mixing bowl.
Thinly slice the cucumbers, either with a knife or a mandoline, and add them to the bowl with the carrots. Toss gently to combine the colorful vegetables.
In a small bowl, whisk together the sesame oil, rice vinegar, honey, and salt until the dressing is smooth and slightly emulsified, releasing a fragrant aroma.
Pour the dressing over the vegetables and toss thoroughly to coat every piece evenly, ensuring the bright colors are well-coated and slightly glazed.
Heat a pan or toaster oven and lightly toast the sesame seeds until they turn golden brown and release a nutty aroma—this takes about 2-3 minutes. Shake or stir frequently to prevent burning.
Sprinkle the toasted sesame seeds generously over the salad, adding crunch and aroma with each bite.
Give the salad a final gentle toss to distribute the sesame seeds evenly and allow the flavors to meld for about 5 minutes before serving.
Serve the sesame carrot cucumber salad in bowls, enjoying its crisp texture, vibrant colors, and balanced tangy, nutty flavors.
