Place sunflower seeds and oats in a food processor and pulse on high until a fine grain is created. Add dates, salt, cocoa powder, and vanilla extract to the food processor and pulse until a fine mixture is created. While running, add water one tbsp at a time until mixture comes together. It should stick together when pinched between your fingers but not be wet or too sticky to handle. Roll in the palms of your hands into two bite balls. Press cacao nibs in the outside of the balls (about 6 per ball). Refrigerate to firm up and store in refrigerator. Makes 15 two-bite cookie dough balls.
