01 - Preheat the oven to 340°F and line a baking sheet with parchment paper. Spread the cooked, dried quinoa evenly on the sheet and bake for 15 minutes, stirring once halfway, until dry and crisp. Let cool completely.
02 - Place the chopped dark chocolate in a heatproof bowl over a pot of simmering water using the double-boiler method, or microwave in 30-second bursts, stirring 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 with the back of a spoon. Space slightly apart to prevent sticking.
05 - Refrigerate for 30 minutes, or until fully set and crisp. The crisps should hold their shape when lifted from the tray.
06 - Enjoy immediately or store in an airtight container at room temperature for up to 1 week. For longer storage, keep refrigerated.
