Cook the noodles by bringing a pot of water to a rapid boil. Add the rice noodles and cook according to package instructions, typically around 5-7 minutes, until tender but slightly firm. Drain and rinse under cold water, then set aside in a large mixing bowl.
While the noodles are cooking, wash and prepare the vegetables. Thinly slice the red bell pepper, julienne the cucumber, grate the carrot, and diagonally slice the green onions. Combine all the chopped vegetables in the mixing bowl with the cooled noodles.
In a small bowl, whisk together the soy sauce, sesame oil, rice vinegar, sriracha, and honey or maple syrup until smooth. Adjust the heat by adding more sriracha if desired.
Pour the dressing over the noodles and vegetables in the mixing bowl. Gently toss until everything is evenly coated.
Sprinkle the toasted sesame seeds and chopped cilantro over the salad. Toss gently once more and season with salt and pepper to taste.
Cover and chill in the refrigerator for about 30 minutes before serving to allow flavors to meld.
Notes
For optimal flavor infusion, chill the salad before serving.
