Method:

1. Combine the vinegar and sugar in a non-reactive bowl along with 2 Tbsp of water. Mix to combine until the sugar has dissolved. Add the grated carrot and steep in the refrigerator while the pork is cooking. Remove just before serving.
2. Lay out the pork belly skin side up on a baking tray and salt the skin generously. Ideally, place it into the fridge, uncovered overnight to dry out the skin.
3. Preheat the oven to 240C.
4. Wipe any excess moisture off with a paper towel. Salt the pork generously on the flesh and the skin, rubbing it in well to ensure it crisps nicely when cooked. Place in the oven for about 30 minutes or until the skin is bubbled and crispy. Reduce the heat to 160C and cook for a further 20-30 minutes or until the pork is cooked through but still juicy. Remove the pork from the oven and allow to rest for 30 minutes before carving it into 1 cm slices.
5. Cut the rolls in half horizontally without going all the way through. Open the rolls up and scoop out a bit of the soft bread centre. Spread a decent amount of pate on the bottom half, and mayonnaise on the top half. Add the sliced pork, followed by the cucumber, pickled carrot, spring onions and coriander. Season to taste with Birdseye chillies and Maggi seasoning, and serve.
