If I have a ton of work, soba noodles are one of my go-to quick meals. In cases such as this, I simply garnish the noodles with some sliced scallions and prepare a little bowl of soy sauce and a touch of sesame oil for dipping - that's it, done, slurp down some noodles, and get back to work.
If you have a little more time, and I'm not talking hours here - maybe 30 minutes, you can jazz up soba with shrimp, edamame, carrots and scallions to create a healthy and flavorful bowl of noodles.
