This salad can be as mild or spicy as you like so adjust the amount of chile to your taste. Black sesame seeds add a nice contrast to the cucumber. If you can’t find black sesame seeds, use regular sesame seeds.
With a veggie peeler, peel lengthwise down the cucumber to create long wide strips. Turn the cucumber after several strips, to use another side. Place cucumber strips in a medium-sized bowl. Discard inner section of cucumber with seeds. Add the sliced chiles, mint and cilantro to the cucumber. Set aside.
In a small bowl, mix the rice wine vinegar, fish sauce and sugar. Place grated ginger on a spoon and with another spoon squeeze the juice out into the dressing. Discard ginger pulp. Stir to combine.
Toss dressing with the cucumber strips, herbs and chile. Sprinkle with black sesame seeds. Serve immediately.
