Cook the noodles as per pack instructions. Rinse in cold water and drain, drizzling with a little bit of oil to stop them sticking together and season with a pinch of salt. Add them to a large bowl.
Dice the cucumber and finely slice the spring onion. Cut the mango into chunks. Add them all to the noodles along with the edamame and coriander. Mix everything together.
Add the peanut butter, lime juice and water to a small bowl and mix together until combined. It should turn creamy and be a drizzling consistency. Add the soy sauce and lime zest and mix again. If too thick at this point, thin down with a splash of water.
Pour the dressing over the noodles and mix everything together. Add your toppings, serve and enjoy!
