Prepare quinoa according to the "How to Cook Quinoa" (recipe link above), adjusting water measurements in line with this recipe.
When the water has all been absorbed, pour in the milk and add cinnamon. Bring to the boil again. Turn to medium-low but don't cover. Cook for a further 30 minutes.
Make sure you stir every so often. The mixture will form a skin if left unattended for too long but just mix it back in.
When the mixture resembles a creamy porridge substance, remove from the heat. Add the chia seeds and ground flaxseed and sweetener.
Top with anything you like! I used banana, dessicated coconut, and pecan nuts.
