Mix all the ingredients in a large bowl. Remove 2 or 3 tablespoons of the marinade and set aside for basting the pork during cooking.
Add the pork to the bowl and coat it well with the marinade.
Cover the bowl with cling film or place in a food bag and refrigerate while you heat up the BBQ (you can make these up the day before to save time if you want).
Spray both sides of the pork with low calorie cooking spray and cook on a hot BBQ for 2 minutes on each side. Turn the BBQ down to a medium heat (or move the pork to a slightly cooler part of the grill).
Cook for 5 or 6 minutes on each side (basting with the reserved sauce halfway through cooking each side) or until the internal temperature reaches 75°c (170 °f).
Serve with your favourite BBQ side dishes.
Preheat the oven to 180°c.
Stray an oven tray with low calorie cooking spray, place the pork on it and cook for 20 minutes - making sure to baste at the 10 minute mark.
Depending on the thickness of your pork, it may need a little longer. Make sure the pork is cooked through before serving.
