Slice fresh cucumbers into ¼-inch rounds and place in a mixing bowl. Sprinkle generously with salt and toss to coat.

Let the salted cucumber sit for 10-15 minutes to draw out moisture.

Rinse the cucumber under cold water 2-3 times to remove excess salt, then drain thoroughly.

In a large bowl, combine minced garlic, fish sauce, sugar, and red pepper flakes, stirring until sugar is dissolved.

Add drained cucumbers, julienned carrots, and chives to the marinade, tossing gently to coat.

Serve immediately or chill in the refrigerator for 30 minutes before serving. Top with sesame seeds if desired.
