This could be as easy as just making the dressing and tossing with the noodles, but you can also add various combinations of vegetables. My favorite vegetables in this salad are thinly sliced shallots and green peas.
Soba noodles are found in the Asian section of most large grocery stores nowadays. They are traditionally made with buckwheat flour, but I've noticed a lot of the brands have part buckwheat flour and part wheat flour. If you can find 100% buckwheat flour soba noodles you should give them a try if you like sea vegetables because they do taste a little like wakame and have an interesting almost slimy texture. The ones that include wheat flour are more mild and grainy.
8 oz. dry soba noodles, cooked according to package directions
1/4 c. seasoned or brown rice vinegar
1/4 c. natural peanut butter
1 Tbsp. (overflowing) shoyu, tamari or low sodium soy sauce
1 tsp. (or more) sriracha (found in the Asian section of most grocery stores, it's a lovely Asian hot sauce)
Small drizzle each of toasted sesame oil and pure maple syrup
About 1 tsp. fresh grated ginger (optional but really good)
1 thinly sliced shallot or red onion
1/2 c. green peas, thawed by running under hot water in a strainer (if using frozen)
1) Cook the soba noodles according to package directions, drain in a colander and rinse with cold water until the pasta is completely cooled.
2) As the noodles cook, whisk together everything but the vegetables in a large bowl.
3) When the noodles are finished cooking and have been rinsed under cold water add them, along with the peas and shallots, to the dressing and toss to coat.
Eat immediately or chill first. This makes 4-6 servings, depending on how hungry everyone is and what else you're eating.
