1. Prepare the Filling: In a mixing bowl, combine the finely chopped apple pie filling with cinnamon, nutmeg, sugar, and lemon juice. Stir well to ensure the mixture is thoroughly blended. This enhances the flavor, making each wonton burst with apple pie taste.

2. Assemble the Wontons: Lay a wonton wrapper flat on your work surface. Spoon about one tablespoon of the apple mixture into the center of the wrapper. Be careful not to overfill to avoid leaks during cooking.

3. Seal the Wontons: Moisten the edges of the wonton wrapper with a little water, using your finger or a small brush. Fold the wrapper over the filling to form a triangle, and press the edges together firmly to seal. This step is crucial for keeping the filling inside while they cook.

4. Prep the Air Fryer: Preheat your air fryer to 350°F (175°C). This ensures the wontons will start cooking at the right temperature for a crispy exterior.

5. Cook the Wontons: Spray the air fryer basket with cooking spray to prevent sticking. Place the wontons in a single layer in the basket. Spray the tops lightly with cooking spray. Cook for 8-10 minutes or until golden brown and crispy. You may need to cook in batches depending on the size of your air fryer.

6. Serve Immediately: Remove the wontons from the air fryer and dust with powdered sugar if desired. Serve hot for the best texture and flavor.
