Spray the basket of an air fryer with cooking oil spray. Place hash browns in basket and spray with oil. Cook on 200°C for 8 minutes, turn over, spray with oil and cook for a further 6-8 minutes or until crisp and golden.

While the hash browns are cooking, heat oil in a non-stick frying pan over medium high heat and fry eggs for 3 minutes or until edges are crispy and yolk is still runny.

Place one hash brown onto serving plate and top with slices of avocado and fried egg. Sandwich with remaining hash brown.

If using chilli flakes sprinkle over the hot egg. Serve immediately.
