To cook the pork fillets, preheat the oven to 180℃, then heat a heavy based oven proof frypan over a medium heat. Add the vegetable oil, and then add the pork fillets cooking on all sides until browned, turning occasionally so that the marinade does not burn. Place the pan in the oven and cook for seven minutes, remove from the oven, and allow to rest for five minutes before slicing and serving.
Heat the leftover marinade to the boil in a small saucepan. Add the sugar and simmer on medium heat for 5 minutes.
Serve the pork fillet with the couscous and herb salad, garnish with the sliced spring onion, green chilli & drizzle a tablespoon of the sauce on top.
