Check your puffed quinoa. In order for the quinoa crisps to be crunchy, it needs to be crisp, but I find a lot of brands of puffed quinoa are more chewy than crisp, so I added a step to toast it to make sure it is lovely and crunchy. If your quinoa is already perfectly crisp, you can skip the toasting.
Put the puffed quinoa in a dry frying pan over medium heat, stirring frequently for a few minutes until it is dried out and crispy. Do not let it burn.
Chop the chocolate finely and place ⅔ of it in a plastic bowl. Microwave in 30-second bursts, stirring well in between, until it is totally melted.
Add the remaining third of the chocolate to the bowl and stir it in vigorously with a spoon until melted. This works best if your chocolate is finely chopped, but if you are left with any unmelted lumps, you can just remove them.
Pour the toasted quinoa into the melted chocolate along with the sea salt and mix everything together until completely coated.
Scoop out teaspoon-sized dollops of the mixture and place onto a baking sheet lined with parchment paper. Use the back of the spoon to press them down into flat disks.
