Bring a medium sized pot of water to a boil then cook the noodles according to the package instructions. Drain and rinse with cold water.
Meanwhile, whisk the tamari, vinegar, lime juice, sesame oil, maple syrup, ginger, and cayenne until well combined. Taste, and adjust the ingredients to your liking.
Fold the sauce into the cooked noodles, along with the edamame, carrots, bell pepper, and cucumber.
Top with green onion and seasoned sesame, if you wish.
