Begin by cooking the rice noodles according to package instructions. Once cooked, drain and rinse under cold water to stop the cooking process. Set aside.
In a medium bowl, combine the peanut butter, soy sauce, sesame oil, maple syrup, and sriracha. Whisk together until smooth and creamy. If the dressing is too thick, add a tablespoon of warm water to thin it out.
In a large mixing bowl, combine the cooked rice noodles with the sliced bell pepper, julienned carrot, julienned cucumber, and chopped green onions.
Pour the peanut dressing over the noodle and veggie mixture. Gently toss everything together until evenly coated.
Add the chopped cilantro and toss again lightly.
Serve the salad in bowls, garnished with crushed peanuts on top for added crunch.
