01 - Preheat oven to 340°F and line a baking sheet with parchment paper. Spread the cooked, dried quinoa evenly on the sheet. Bake for 15 minutes, stirring once halfway through, until dry and crisp. Let cool completely.
02 - Place chopped dark chocolate in a heatproof bowl over a pot of simmering water using the double-boiler method. Alternatively, microwave in 30-second bursts, stirring between intervals until completely smooth.
03 - Mix the cooled, toasted quinoa into the melted chocolate until well coated. Add sea salt and any desired add-ins such as toasted nuts or shredded coconut.
04 - Drop heaping teaspoons of the mixture onto a parchment-lined tray, shaping into small rounds about 2 inches in diameter. Space slightly apart to prevent sticking.
05 - Refrigerate for 30 minutes or until fully set and firm to the touch. The crisps should break cleanly when handled.
06 - Enjoy immediately or store in an airtight container at room temperature for up to 1 week. For longer storage, keep refrigerated for up to 2 weeks.
