01 - Preheat oven to 340°F and line a baking sheet with parchment paper. Spread cooked, dried quinoa evenly on sheet. Bake for 15 minutes, stirring once halfway through, until dry and crisp. Allow to cool completely.
02 - Place chopped dark chocolate in heatproof bowl over pot of simmering water using double-boiler method. Alternatively, microwave in 30-second bursts. Stir continuously until completely smooth and glossy.
03 - Fold cooled, toasted quinoa into melted chocolate until thoroughly coated. Sprinkle sea salt over mixture and incorporate any desired optional add-ins such as toasted nuts or shredded coconut.
04 - Drop heaping teaspoons of chocolate-quinoa mixture onto parchment-lined tray. Gently shape into small rounds using back of spoon, spacing slightly apart to prevent sticking.
05 - Refrigerate tray for 30 minutes or until crisps are completely firm and set. Test by gently touching center of crisp to ensure solid texture.
06 - Serve immediately or transfer to airtight container. Store at room temperature for up to one week. For best texture, keep away from direct sunlight and heat sources.
