Step 1

Make Creamy Avocado Dipping Sauce: Place avocado, juice, yoghurt, pesto and onion in a small food processor. Season well with salt and pepper. Process until smooth and combined. Transfer to a bowl. Cover. Refrigerate until required.

Step 2

Line a large tray with baking paper. Place flour and garlic powder in a shallow bowl. Season with salt. Whisk eggs in a separate shallow bowl. Combine breadcrumbs in a bowl.

Step 3

Cut mozzarella into 2cm-thick slices, then into sticks. Dip cheese in flour to coat. Shake off excess. Working in batches, coat sticks in egg mixture then in breadcrumbs. Place on prepared tray. Freeze for 1 hour or until firm.

Step 4

Spray mozzarella sticks liberally with oil. Line air fryer basket with baking paper, leaving a 1cm edge to allow air to circulate. Cook sticks on 180C, in batches, for 4 to 4 1/2 minutes or until golden and crispy. Serve immediately with dipping sauce.
