1 avocado,pitted & peeled
½ garlic clove, smashed
½ bunch scallions, roughly chopped
juice of ½ lemon
5 cl extra-virgin olive oil
salt & freshly ground black pepper

Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente, 6 to 8 m.
While the pasta cooks, make the sauce: In the bowl of a food processor, pulse the avocados, garlic, scallions, lemon juice and olive oil until smooth.
When the pasta is tender, reserve 5 cl of the cooking water, then drain the pasta. Add the reserved water to the avocado mixture and process until smooth.
Add the sauce to the pasta and toss to coat. Season with salt and pepper.

To serve, portion the pasta onto plates and garnish with parsley.
