Place all of the marinade ingredients into the Thermomix bowl and blend 10 sec/speed 10.
Pour over pork fillet to marinate for at least 1 hour.
Heat the EVOO in either a wok, or electric frying pan or similar. Saute the garlic and onions until just browning and very fragrant. Push to one side of the pan, away from the heat. Add the somewhat drained pork pieces and cook these until they are browning well on the outside. Cook a further 5 minutes, scraping the stickiness from the pan, add in the drained marinade. We added around a cup of water, just to keep everything moving well around the pan.
Add the capsicum strips and pineapple and cook for 5 minutes. Serve immediately over rice, sprinkled with sesame seeds, and garnished with loads of coriander...unless that is not your favourite. In which case, use some herbs of your choice.
