Combine all the marinade ingredients and mix well.
Spread over the chicken on both sides and allow to marinade for up to 24 hours but at least 1 hour.
Grill in a hot griddle pan with the lemon halves (alternatively cook the chicken on a barbecue) for 7-10 minutes per side then transfer to the oven (pre-heated to 180ºc) and cook for a further 20 minutes or until the chicken is cooked through.
