For this recipe, you might want to overcook your quinoa a bit. It will help the burgers hold together better. In any case, you want to bring a pot with 1 cup of water, and 1/2 cup dry quinoa to a boil. Reduce the heat to a simmer, and continue simmering until all the liquid is gone; about 20 minutes. Remove the pot from the heat, and put on the lid. Let it sit for at least 10 minutes before fluffing with a fork and using. Some quinoa brands require a quick rinse before you start cooking, and some don't. Read the package beforehand, or just rinse it anyway to be on the safe side.
