Preheat the air fryer to 210-220˚C or max crisp setting.
Season the pork belly pieces with salt and place in the air fryer basket.
Air fry for 18-20 minutes until fully cooked and crispy skin has been achieved.
In the meantime, combine the soy sauce, 5 spices, rice wine vinegar, sesame oil fish sauce , pinenuts and cashew crush into a glaze. Add some honey and lime if desired to add flavours.
Once the pork belly pieces are cooked and crispy, remove from the air fryer and toss in with the glaze.
Toss to coat the flavour on the belly bites and serve immediately with salad leaves.
