Bring a large pot of water to a boil. Add noodles and cook until just al dente, 6 to 8 minutes. Drain.Advertisement
Heat 1 tablespoon oil in a wok or large deep skillet over high heat until very hot. Add garlic and stir-fry until golden, about 10 seconds. Add eggs and cook, stirring, until scrambled, about 30 seconds. Add shrimp and the remaining 1 tablespoon oil; stir-fry until the shrimp curl and turn pink, about 2 minutes.
Add the noodles, bean sprouts, scallion greens, vinegar, fish sauce, brown sugar and crushed red pepper; toss until heated through, 1 to 2 minutes. If desired, sprinkle with peanuts and serve with lime wedges.
For sustainable shrimp, look for shrimp that's certified by an agency like the Marine Stewardship Council. If you can't find it, choose wild-caught shrimp from North America--it's more likely to be sustainably caught.
