01 - Bring a pot of water to a boil. Add edamame and cook for 3–5 minutes until tender. Drain and rinse under cold water to stop cooking.
02 - Slice cucumbers thinly and place in a large mixing bowl. Sprinkle with a pinch of salt and let sit for 5 minutes, then pat dry with a paper towel to remove excess moisture.
03 - In a small bowl, whisk together soy sauce, rice vinegar, sesame oil, sugar, grated ginger, and minced garlic until smooth and well combined.
04 - Add cooked edamame, sliced cucumbers, and green onions to the mixing bowl. Drizzle with dressing and toss gently to coat evenly.
05 - Transfer to a serving dish and garnish with toasted sesame seeds and cilantro, if using. Serve immediately or refrigerate until ready to serve.
