Bring a medium saucepan of salted water to the boil. Add pasta and set timer for the cooking time stated on the packet.

When there are 3 minutes to go, add peas.

When the timer is up, reserve some cooking water in a cup. Drain.

Return the pan to the heat and add 2 tablespoons olive oil. Add pasta, peas and mint.

Stir in ricotta, adding a little of the cooking water if it seems too dry.

Taste, season and serve with parmesan.
