Soba noodles are made of buckwheat flour and have a toasty, nutty flavor. You can sub whole-wheat linguine if you can't find them.
Prepare soba noodles according to package directions. Drain; rinse under cold water. Drain.
Combine soy sauce, vinegar, oil, and hoisin sauce in a large bowl, stirring with a whisk. Add noodles; toss. Sprinkle with green onions and sesame seeds.
Perfect to accompany any Asian style main dish in place of rice. Tonight I steamed some potstickers and served it with a Thai cucumber salad. Easy to prepare and goes together quickly. I added some cilantro at the end for color. Will make again.
