Look for soba noodles on the Asian food aisle. If you can't find them, you can sub whole-wheat spaghetti (which takes about 10 minutes longer to cook).
Cook soba according to package directions, omitting salt and fat; drain and rinse with cold water. Drain well.
Combine soy sauce, dark sesame oil, brown sugar, lemon juice, and crushed red pepper in a medium bowl, stirring well with a whisk. Add noodles, red bell pepper, snow peas, and green onions; toss well.
