In a small bowl, whisk together applesauce, honey, and vanilla extract. Set aside.
In a large bowl, toss together pecans, oats, apple pie spice, cinnamon, and salt. Pour applesauce mixture over the oat mixture and toss to combine.
Spray inside of a large (6-quart) slow cooker with cooking spray. Add oat mixture to the slow cooker. Cover, and cook in a vented slow cooker (I just left my lid slightly ajar to let the steam escape) on high for 3 ½ hours, stirring every 30 minutes.
After the first 3 ½ hours, add the dried apples and the raisins to the slow cooker. Stir, and cook for an additional 30 minutes.
Spread the granola onto waxed paper and cool completely. Store in airtight containers.
