If cooking the pork immediately (without marinading in the fridge) preheat the oven to 180C/Fan 160C/350F/Gas Mark 4.
In a small bowl, mix together all of the ingredients except the pork belly and lemon wedges.
Rub the marinade mixture all over the pork belly slices. If you have time, cover and leave in the fridge for 2-3 hours, or overnight. Otherwise, skip straight ahead to the next step.
Place belly slices in a roasting tin. Roast the marinaded pork belly slices in the preheated oven for 35 minutes.
Allow to rest for 5 minutes before serving.
