Cook the rice noodles according to the package instructions. Drain and rinse under cold water to stop the cooking process. Set aside.
In a medium bowl, whisk together the peanut butter, soy sauce, rice vinegar, lime juice, honey or maple syrup, minced garlic, and ginger. Add warm water, a little at a time, until the dressing reaches your desired consistency.
In a large mixing bowl, combine the cooked rice noodles, julienned carrots, julienned cucumber, and toasted almonds.
Pour the peanut butter dressing over the noodle mixture. Toss everything together until well coated.
Serve immediately, garnished with fresh cilantro, green onions, and a sprinkle of red pepper flakes or a drizzle of sriracha if desired.
