Berry Applesauce

6 large apples (I used Royal Gala apples), peeled and sliced
1 cup strawberries, sliced
1 cup blueberries, fresh or frozen
1/4 cup unsweetened applejuice
2 tablespoons lemon juice

Place ingredients in a crockpot and cook on low for 6-8 hours. After cooking, blend with an immersion blender, or simply mash them for a chunkier sauce.
