Place quinoa in a mesh colander. Rinse thoroughly with cold water (until the water runs clear) and allow to drain.
In a medium pot, combine the quinoa, milk, maple syrup, cinnamon, and salt. Bring to a boil over medium heat. Reduce heat to a low simmer and cover, leaving the lid cracked so that some steam may escape. Simmer for 25 minutes, stirring about every 5 minutes.
Remove the lid and continue simmering for 5 more minutes or until the pudding has thickened and the quinoa has absorbed most (but not all) of the milk. Remove from heat, now add your vanilla & stir in.
Pour into bowls and allow to cool for a few minutes before serving (pudding will continue to thicken as it cools). Will thicken up beautifully once refrigerated overnight. Sprinkle with additional cinnamon, if desired.
Keep refrigerated up to 3 days
