Put the quinoa in a small saucepan and add 180ml water.
Bring to a boil, cover and turn the heat to low.
Simmer for 10 minutes, then remove from the heat and set aside with the lid still on for 10 minutes more.
Remove the lid and leave to cool down.
Transfer the cooled quinoa to a large bowl and add the remaining ingredients, including three-quarters of a teaspoon of salt and some black pepper.
Stir everything together and serve.
