Heat a large saucepan of water over high heat until boiling. Add the pasta and cook as per packet directions or until al dente. Drain and refresh.

Meanwhile, place avocado, lemon juice, rind, olive oil, salt and pepper in a large mixing bowl.

Use a fork to roughly mash the avocado and combine with the lemon juice dressing.

Add the hot pasta to the avocado and mix until well coated, add basil leaves and prosciutto (trimmed of fat). Toss before serving with parmesan shavings.
