Put the noodles in a large bowl and cover with boiling water. Let the noodles soak until tender, about 10 minutes; drain and rinse under cold water until cool. Transfer to a serving bowl.
Whisk the lime juice, soy sauce, peanut butter, brown sugar and vegetable oil in a medium bowl until smooth. Pour the dressing over the noodles. Add the bell pepper, scallions, basil, cilantro and mint and toss to combine. Season with salt and sprinkle with the peanuts.
