- In a medium pot, bring water to a boil. Add the green beans and cook for 3-4 minutes until tender-crisp. Drain and immediately transfer to a bowl of ice water to stop the cooking process. Once cooled, drain again and set aside. 
- In a large bowl, combine the chickpeas, black beans, green beans, red bell pepper, corn, red onion, and cilantro. 
- In a separate small bowl, whisk together the miso paste, sesame oil, rice vinegar, soy sauce, honey or maple syrup, ginger, and garlic until smooth. Season with salt and pepper to taste. 
- Pour the dressing over the bean mixture and toss gently to combine. 
- Chill the salad in the refrigerator for at least 30 minutes before serving to allow the flavors to meld. 
- Serve chilled or at room temperature.
