Simmer for 20 minutes. (I recommend using a timer) Make sure all water is gone. You can cook it for a couple more minutes if not.
When finished cooking, remove from heat and let sit with the lid on for 15 more minutes.
When quinoa is finished cooking, stir in the poblano and Manchego.
Spread onto a platter or bowl and top with the corn, tomatoes, cilantro and a little Manchego.
