Bring a small pot of water to a boil. Add a pinch of salt and cook the noodles, then drain and rinse them under cold water to cool them down. Add a little soy sauce to the noodles and mix well.
While the noodles are cooking, peel the carrot and cut it into thin sticks. Peel the cucumber, remove the seeds and cut it into thin sticks as well. Slice the avocado and salmon so you have enough for all the rolls.
Start assembling the rolls. Soak one sheet of rice paper in water, following the instructions on the package, then place it on your work surface. Place a slice of salmon slightly below the centre of the sheet. Add some noodles on top, then some carrot, cucumber and a slice of avocado.
Gently fold the bottom edge up over the filling. Fold in the sides. Then roll it up tightly.
