Pour 4 cups of water in a medium pot and set on the gas top. Turn on the heat to high and bring the water to a boil.
Meanwhile, prepare the sauce. Open the packet of the sauce into a small bowl and mix with peanut butter.
When the water comes to a boil, cook the noodles for 1 minute or until preferred texture. Drain the noodles and wash under running water to wash off excess starch.
Transfer the noodles into a serving plate and place the toppings as you like.
Serve with the sauce from Step 4. Enjoy!
