Place the quinoa in a small pot with the water and make it break into a bowl over medium heat.
Put a lid on the pot and reduce the heat to a minimum. Let it cook until it's dry, about 15 minutes.
Remove the quinoa from the pot and let it cool down completely.
Add the olive oil, parmesan cheese, salt and pepper and mix.
Pour the mix onto a baking tray lined with baking paper. Place in a preheated oven at 180°C / 350°F for 30-50min. Mix the quinoa every 10 minutes.
Once you see that it starts to become golden, you can remove the paper, it won't stick anymore. From this point on, check every 5 minutes because it goes from golden to burnt in a heartbeat.
Remove from the oven and let it cool down completely. If you have large bunches of quinoa, separate them by crushing them with the back of a fork.
