In a saucepan, heat the olive oil over medium heat. Add the chopped onion and sauté until translucent.

Add the Arborio rice and stir for a couple of minutes until the rice is slightly toasted.

Gradually add the warm vegetable broth, one ladle at a time, stirring continuously until the liquid is absorbed.

When the rice is creamy and al dente, stir in the fresh peas and Parmesan cheese. Season with salt and pepper.

Serve hot, garnished with additional Parmesan if desired.
