Rinse quinoa and cook as directed on package. Typically a 1:3 ratio of uncooked quinoa to water is required.
If there are no package directions, combine quinoa, water, and salt in a very large pot with a lid. Bring to a boil over high heat. Once it boils, reduce heat to medium low. Keep covered and simmer for 20 minutes or until water is absorbed.
Remove from heat and let stand, covered, for 5 minutes. Fluff with a fork and let cool completely.
Using a measuring cup, scoop 1-2 cup portions into freezer bags and label with measurement. Flatten and freeze for up to 10 months.
