Boil a pot of water. Add the soba rice noodles and cook al dente, about 7 minutes. Drain in colander and rinse with cold water. (Cross check cooking time w/package instructions.)
Shred the vegetables using a microplane or knife and transfer to bowl big enough to toss with juice from half a lime and several spoonfuls of the peanut sauce to lightly dress. Serve additional peanut sauce on the side and save remaining, refrigerated, for another use within a few days.
Assemble bowls with dressed noodles and top with chilled poached shrimp, salted peanuts, additional cilantro or mint leaves, and a lime wedge.
