Cook the risoni in a large saucepan of boiling water according to packet instructions. Add the peas to the pan for the final 3 minutes of cooking time. Rinse the pasta and peas under cold water, then drain well and place in a large bowl.
While the pasta is cooking, blend all the mojo ingredients in a blender until smooth. Season well with salt and pepper.
Stir a third of the mojo into the pasta with the lemon zest and juice, oil, paprika, pine nuts, spring onion and coriander. Flake the salmon with a fork, then add to the pasta and gently stir through. Season to taste with salt and pepper. Serve the pasta with the remaining mojo to drizzle.
