Marinade: In a bowl, combine all the ingredients.
Place the butterflied chicken in a roasting dish and brush half of the marinade on both sides. Cover and refrigerate for 2 hours.
Pickled Cucumber Salad: Place the cucumber in a large bowl with the remaining ingredients. Toss to combine then cover and refrigerate until you’re ready to serve. Preheat a lidded barbecue to medium.
To serve: Serve the chicken with sticky white rice, pickled cucumber salad, toasted sesame seeds, coriander leaves and, if desired, sliced chilli.
Cook’s note: If you don’t have a lidded barbecue, you can grill the chicken on the barbecue first and finish cooking it in the oven. Preheat the oven to 190ºC regular bake. Grill the chicken on both sides for a few minutes then place in a roasting dish and bake for 60 minutes or until the chicken is cooked through and juices run clear.
