Begin by washing the cucumbers under running water. Peel if desired, then slice them into thin rounds or half-moons.

In a large mixing bowl, add the sliced cucumbers, red bell pepper, chopped red onion, and grated carrot.

In a separate small bowl, whisk together the lime juice, fish sauce (or soy sauce), sugar, and chili flakes until the sugar is dissolved.

Pour the dressing over the vegetable mixture and gently toss until everything is well coated.

Add the chopped cilantro and toss lightly to combine, saving a sprinkle for garnish on top.

Let the salad sit for 5-10 minutes before serving, allowing the flavors to meld together.
