Preheat the oven to Gas Mark 1, 140°C.
To cook the pork: Mix the ingredients for the sauce in a medium sized bowl. Dry the pork slices with kitchen paper, season with salt and pepper then add them to the bowl with the sauce. Mix well. Line a roasting tin with tin foil then lay the pork slices in a single layer in the roasting tin. Cover tightly with foil and roast for an hour and a half.
Remove the foil, spoon over the liquid. Increase the oven temperature to Gas Mark 6, 200°C and cook for a further 8-10 minutes turning the pork slices halfway through and brushing over the liquid from the roasting tin, until the sauce is thick and sticky.
To cook the fried rice: Add the sesame oil to a wok or large frying pan. Then add the ginger and chilli and stir for a minute. Add the cold rice and stir to break up any lumps. Mix the eggs with the oyster sauce and soy sauce and then add this mixture to the wok. Stir well and allow to cook for a minute or two. Add the scallions and coriander, taste and season.
To serve: Divide the rice between four plates. Place the slices of pork on top and spoon over any sauce from the roasting tin.
