Rinse the quinoa well in a fine-mesh strainer under cool running water for 30-60 seconds to remove its natural bitter coating.
In a medium saucepan, combine the rinsed quinoa, coconut milk, water, vanilla extract, ground cinnamon, and nutmeg. Bring to a gentle boil over medium-high heat while stirring frequently.
Once boiling, reduce the heat to low, cover the pan partially, and simmer, stirring occasionally, until the quinoa is tender and most of the liquid is absorbed, 15 to 20 minutes. The porridge should look thick and creamy, like loose oatmeal.
Remove from heat and stir in the honey. Taste and adjust sweetness. If you prefer a looser, more pourable texture, stir in a splash or two of water.
Divide the porridge into bowls. Top with fresh berries or other fruit and serve warm.
