In bowl, soak noodles in enough cold water to cover until pliable, about 5 minutes; drain. In large saucepan of boiling salted water, cook noodles until tender, 1 to 2 minutes. Remove with tongs and chill under cold water; drain and cut into 1-inch/2.5 cm lengths. Place in large bowl. Add pork to saucepan; cook, breaking up with spoon, until no longer pink, about 1 minute. Drain in sieve and rinse briefly under cold water; drain and let cool. Add to noodles.

Slice cucumber as thinly as possible; stack into small piles and slice crosswise as thinly as possible into fine julienne (or use mandoline). Add to noodles. Repeat with carrot; add to noodles. Slice red onion as thinly as possible; cut slices into 1/4 inch/5 mm lengths. Add to noodles with coriander and mint.

In small bowl, mix lime juice, fish sauce, ginger, hot peppers and sugar; pour over noodle mixture and mix well. (Make-ahead: Refrigerate for up to 2 hours.) Transfer to serving platter; sprinkle with peanuts.
