Step 1

In a large bowl, combine the tomatoes, soy sauce or tamari, rice vinegar and sesame oil. Stir well and let marinate while the edamame and noodles cook.

Step 2

Bring a large pot of water to a boil over high heat. Add the edamame and then the soba and cook until the soba is just tender, but still has some bite, 4 to 5 minutes. Drain. Toss with the tomatoes until well coated.

Step 3

Taste, and add more soy sauce and/or vinegar, if desired. Divide among four bowls and serve, with sesame seeds sprinkled on top.
