Begin by cooking the glass noodles according to the package instructions. Typically, this involves soaking them in hot water for about 10-15 minutes until soft. Drain and rinse under cold water to stop the cooking process. Set aside.
In a large mixing bowl, combine the shredded carrots, shredded red cabbage, cucumber, bell pepper, cilantro, and green onions. Toss to mix evenly.
In a separate bowl, whisk together the soy sauce, rice vinegar, sesame oil, honey or maple syrup, minced garlic, grated ginger, and crushed red pepper flakes until well combined.
Add the cooked glass noodles to the vegetable mixture and pour the dressing over the top. Toss everything together gently until the noodles and vegetables are evenly coated in the dressing.
Let the salad sit for about 10-15 minutes to allow the flavors to meld. If desired, top with chopped roasted peanuts before serving.
