Cook the quinoa as per packet instructions. Rinse, drain excess water (it would work even better with leftover quinoa). The quinoa needs to be very dry before starting the next step.
Add all the ingredients to a bowl and mix.
Transfer to a baking tin (with baking paper on it) and spread out evenly. Use a large baking tin, don’t overcrowd the sheet pan.
Bake at 180C for minutes 22-25 mins, mixing half way.
