Cook the spaghetti or rice noodles according to package instructions. Drain and set aside, reserving a small cup of the cooking water.
In a large pan, heat the sesame oil and vegetable oil over medium heat. Add the minced garlic and grated ginger, sautéing for 1-2 minutes until fragrant.
Add the sliced red bell pepper and snap peas to the pan, stirring continuously for about 3-4 minutes until slightly softened but still crisp.
In a small bowl, combine the soy sauce, rice vinegar, sriracha, and honey (or maple syrup). Mix well.
Add the cooked noodles to the pan with the vegetables, then pour the sauce over the top. Toss everything together, adding a splash of reserved noodle cooking water if needed for moisture.
Stir in the sliced green onions and toasted sesame seeds, mixing until all ingredients are well combined and heated through.
Serve hot, garnished with fresh cilantro if desired, and additional sesame seeds.
