Boil a pan of water and season with salt. Drop the pasta into the boiling water and cook according to the packet instructions.
Season the salmon fillets with salt and pepper then bake for 8-10 minutes.
Once the pasta is cooked drain it in a colander and run under cold water until it is completely cool.
Add the cooled pasta into a large mixing bowl. Add the mayonnaise, spring onion and cherry tomatoes. Mix well.
Add the zest and juice of the limes, season and mix well.
Flake the salmon, then add two thirds into the mixing bowl along with the avocado and half of the rocket leaves. Mix well.
Layer the remaining rocket onto a large plate or platter, then spoon the pasta salad over the top. Finish by scattering over the remaining pieces of salmon.
