Bring a large pot of water to a boil for the pasta. Meanwhile, finely chop the smoked salmon and sauté it in a skillet with a little extra-virgin olive oil. Remove from heat and stir in the pesto.

Cook the pasta in salted boiling water until al dente. Drain and toss it in the skillet with the salmon and pesto mixture.

Plate the pasta and garnish with a little extra smoked salmon and a sprinkle of freshly ground black pepper.

Serve the spaghetti hot.
