Boil water in a large pot and add shelled edamame; cook for 3-5 minutes until tender.
Drain the edamame and rinse under cold water to stop the cooking process.
In a large bowl, combine cooled edamame, diced red and yellow peppers, and julienned carrot.
Add sliced green onions to the bowl.
In a small bowl, whisk together olive oil, soy sauce, rice vinegar, salt, and pepper.
Pour the dressing over the salad ingredients and toss everything together.
Sprinkle sesame seeds on top for added crunch.
Serve immediately or chill in the refrigerator for 30 minutes for enhanced flavors.
