Method

1. Fill a large pot with lightly salted water and bring to a rolling boil over high heat.
2. Once the water is boiling, stir in the angel hair pasta, and return to a boil.
3. Cook the pasta uncovered, stirring occasionally, until the pasta has cooked through, but is still firm to the bite, 4 to 5 minutes.
4. Drain well in a colander set in the sink.
5. Whisk together the sesame oil, soy sauce, balsamic vinegar, chili oil, and sugar in a large bowl.
6. Toss the pasta in the dressing, then sprinkle with sesame seeds, green onion, and bell pepper.
7. Serve warm, or cover and refrigerate for a cold salad.
