In a large mixing bowl, combine the old-fashioned rolled oats, vanilla protein powder, dried apples, and chopped walnuts. Add ground cinnamon, ground nutmeg, and salt. Mix until well incorporated.

Pour in the almond butter, maple syrup, and unsweetened applesauce. Stir vigorously until everything is well combined. If mixture is too dry, add more applesauce.

Using your hands or a cookie scoop, roll the mixture into 1-inch balls and place on a parchment-lined tray.

Refrigerate for 15-30 minutes to enhance texture. Enjoy your protein balls as a tasty, no-bake snack!
