Sprinkle with ½ teaspoon salt and let sit for 5-10 minutes to draw out excess water.
Rinse off the salt and pat the cucumbers dry with a paper towel.
In a small bowl, mix together soy sauce, rice vinegar, sesame oil, sugar, gochugaru, and minced garlic.
In a mixing bowl, combine the cucumbers, green onions, and sesame seeds.
