Grab some fresh cucumbers from your favorite, local, farmer's market
Slice the cucumbers into 1/4" slices. I like using my mandoline for this task - be sure to use the guard!
Mix the rice vinegar, toasted sesame oil and sugar together in a small cup or bowl
Grate the ginger into the sauce
Chop the scallions and add them, along with the chopped cilantro, to the cucumbers
Add the dressing and mix well. Sprinkle with a few red pepper flakes, if you like. Let sit in the refrigerator for 20 -30 minutes to let the flavors meld
