If noodles were refrigerated, soak package in warm water for 30 minutes to an hour prior to cooking.
Steam rice noodles according to package instructions (I typically steam for 10 minutes or until softened).
In a small bowl, add the hoisin sauce, soy sauce, sugar and water and mix until well blended.
In a separate small bowl, mix the peanut butter with the boiling water. (You may add more or less peanut butter or water, to taste, and mix until desired consistency is reached.)
When noodles are cooked, remove and top with both sauces and optional sesame seeds and/or chili sauce.
Serve immediately. Enjoy!
