Gather and prep your ingredients. Bring a medium pot of water to a boil and cook the soba according to the package instructions. Rinse in cold water and set aside in a medium bowl.
In a small bowl, whisk together the ingredients for the dressing.
Add the scallions and cilantro to the bowl of noodles and start to drizzle with the dressing. Turn to coat and continue adding dressing until it is to your liking. Finish with sesame seeds and enjoy!
