Rinse the quinoa thoroughly under cool running water using a fine-mesh strainer, then drain well.
Add the quinoa and 2 cups of water to a small saucepan and bring to a boil over medium-high heat.
Reduce the heat to low, cover the saucepan, and gently simmer for about 15 minutes, or until the quinoa is tender and the liquid has been absorbed. Add a little of the remaining water if needed during cooking.
Remove the saucepan from the heat. Fluff the quinoa gently with a fork, cover again, and let it rest for 5 minutes.
Stir the vegan margarine and soy milk into the warm quinoa until the mixture becomes creamy.
Add the ground cinnamon and maple syrup, stirring until evenly combined.
Divide the Maple Cinnamon Breakfast Quinoa between serving bowls.
Top with raisins and freshly sliced bananas, if using, and serve warm.
