The only thing I did differently the first time around was boiled the snow peas for maybe two minutes. Then I drained them and ran them under cold water. I don't like mine raw.
Next time I would give the noodles longer to drain so that they don't water down the dressing. I would use more scallions as well. I thought it was tasty but I might try adding the ginger and garlic to the dressing someone else suggested.
