Begin by bringing a large pot of water to a boil. Add the rice noodles and cook according to the package instructions, usually around 4-5 minutes until al dente. Once cooked, drain the noodles and set them aside.
In a mixing bowl, combine the hoisin sauce, peanut butter, rice vinegar, maple syrup, minced garlic, and freshly grated ginger. Whisk together until smooth. If the sauce is too thick, add 1-2 tablespoons of water or vegetable broth to reach your desired consistency.
In a large mixing bowl, toss the cooked rice noodles with the prepared sauce. Make sure all the noodles are well coated in the delicious mixture.
Fold in the sliced green onions and any additional toppings you desire, such as roasted peanuts, cashews, or fresh cilantro. This adds a delightful crunch and freshness to the dish.
Transfer the noodles to serving bowls and sprinkle with sesame seeds, red pepper flakes for a kick, and any other garnishes you enjoy. Serve immediately and dig in!
