Remove the pits from the dates and add them to the food processor. Process until dates have broken down and mixture is fully combined. Add cacao powder and tahini and process until the ingredients start to come together to form a dough. Pulse in the toasted quinoa.
Using a small cookie scoop or spoon, shape the dough into small balls using your hand. (You might have to squeeze them together a few times to really incorporate the ingredients)
