Make the dressing: In a small bowl, whisk together the vinegar, tamari, sesame oil, ginger, garlic, and maple syrup. Set aside.

Bring an unsalted pot of water to a boil and cook the soba noodles according to the package directions. Drain and rinse well in cold water. This helps to remove starches that cause clumping. Toss the noodles with the dressing and divide into 2 to 4 bowls. Squeeze fresh lemon juice onto the avocado slices and add to the bowls along with the snap peas, edamame, radish, mint, and a sprinkle of sesame seeds. Drizzle with more tamari or sesame oil, if desired.
