Wash and pat dry the cucumbers, then trim off their ends.
Lightly smash the cucumbers using the side of a large knife, until they break into sections.
Cut the cucumbers into bite-sized pieces and place into a bowl.
Sprinkle salt onto cucumbers and mix until combined. Allow to sit for 15 minutes, then pour through a sieve or colander to remove excess liquid. Set aside.
In a separate bowl, mix the dressing ingredients together until well blended.
Toss the smashed cucumbers with the dressing.
Top with crushed red pepper flakes (optional but highly recommended), minced garlic and/or black/white sesame seeds. Serve immediately or marinate for 15 minutes before serving.
