Begin by dicing the apple slices and spreading them out on a paper towel to remove as much excess moisture as possible.
Add the remaining ingredients to a mixing bowl. Mix the ingredients together until well combined. Add the apples and stir to evenly distribute.
Measure two tablespoons of the mixture for each ball. NOTE: A medium cookie scoop works well. Place the mixture in your hands and firmly squeeze it into a ball shape. Roll it between the palms of your hands to smooth it out and keep it round.
Serve immediately or refrigerate for up to 2 days in an airtight container.
