Pour the chopped tomatoes straight from the can into a blender bowl and process until smooth or coarse (depending on your preference). If you prefer your sauce to be chunky, just skip this step.

Heat the olive oil in a saucepan over medium heat. Add the chopped onion, grated garlic and a pinch of chilli flakes (optional) and cook for 5-6 minutes, or until soft and translucent.

Pour in the blended chopped tomatoes. Stir well and bring to a gentle simmer.

Season with salt, pepper and oregano. Reduce the heat and let the sauce simmer gently for 20-25 minutes, stirring occasionally, until thickened.

Just before serving, stir through a few torn basil leaves for a fresh, aromatic touch.
