Wash and dry the cucumbers. Chop the cilantro, and slice the green onions.
Combine rice vinegar, salt, toasted sesame oil, ginger paste, garlic paste, soy sauce, sugar, and sesame seeds in a mason jar. Add the lid, and shake until combined.
Place the flat side of a meat mallet against each cucumber on a cutting board. Lightly press with your other hand until the cucumber cracks open.
Cut the smashed cucumbers into bite-size pieces, about 1-inch in diameter.
In a large bowl, mix the cut cucumbers with cilantro and green onions.
Drizzle on the dressing and toss well to combine. Taste and adjust seasonings if needed.
Serve with a drizzle of chili oil or a sprinkle of red pepper flakes. Best enjoyed the same day.
