Place the rolled oats and walnuts into a food processor and pulse until finely ground.
Add the dried apples, pitted dates, cinnamon, nutmeg, vanilla extract, and salt to the food processor.
Process the mixture on high until a sticky dough forms and begins to clump together.
Scoop approximately one tablespoon of the mixture at a time and roll between your palms to form a ball.
Repeat with the remaining mixture until approximately 12 bites are formed.
Store in an airtight container in the refrigerator for up to one week or freeze for longer storage.
