Add dates, oats, walnuts, applesauce, ground flax, cinnamon and sea salt to the food processor. Process until the mixture forms a sticky dough.
Using clean hands, roll the dough into balls (about 1 1/2 tbsp per ball) and roll them in a plate of crushed walnuts or shredded coconut if desired.
Refrigerate for at least 30 minutes then enjoy. Store in an airtight container in the fridge or freezer.
