In medium saucepan, bring quinoa, water, and salt to a boil. Reduce heat to maintain gentle simmer. Simmer, uncovered, about 15 to 20 minutes, or until water is nearly absorbed.
Cover and let steam for 5 minutes. Uncover and fluff with a fork. Spread on rimmed baking sheet to cool. Omit this step if you already have cooked quinoa.
Over medium low heat and stirring frequently, toast pepitas until golden, about 12 minutes. Immediately remove from heat, and spread out on a plate lined with parchment paper to cool.
