Prepare noodles according to package directions. In a small bowl, whisk 2 tbsp warm water, soy sauce, peanut butter, chili sauce, garlic powder, ginger, and hot sauce together until combined. It may appear too runny at first, but it's not. Taste, adding more hot sauce if desired. Using tongs, toss prepared noodles with sauce until all noodles are evenly coated. Plate and top with bean sprouts. Garnish with chopped raw peanuts and a lime wedge if desired.
Chef's Note: For a gluten-free version, use wheat-free tamari in place of the soy sauce.
