Cook noodles according to package instructions. Strain and set aside.
Chop green onions. Rinse and drain edamame beans and let dry. Chop cilantro and peanuts if using.
Add noodles plus rest of ingredients to a large bowl and toss gently until well blended. Serve at room temperature, sprinkle with cilantro and additional chopped peanuts if desired.
It’s super important to check the labels of any jarred sauce you buy. Make sure there are no added chemicals, sugars, HFCS, MSG, or “added coloring”. Citric acid is ok as a preservative but if you see anything you can’t pronounce, put it back on the shelf.
