Combine the thawed edamame, drained and rinsed white beans, diced red cabbage, cucumber, and red bell pepper in a large bowl.
Make the orange-miso vinaigrette by whisking together the miso paste, orange zest, orange juice, soy sauce, rice wine vinegar, sesame oil, honey, garlic, and ginger.
Pour the vinaigrette over the salad and toss to coat.
Optionally, top with minced cilantro and scallions.
Season with additional salt, sesame seeds, and chili flakes to taste.
