Mix all of the ingredients in a large bowl (apart from the bread!)
Slice your bread loaf on an angle, almost down to the base but not quite.
Using a fork, stuff the mix in each of the gaps as best you can, pushing it down as far as you can.
Wrap the whole loaf in tin foil, creating a large, sealed boat.
Preheat the BBQ to 180°C, then pop on the bread and close the lid. After 5 minutes, open up the foil package to expose the top of the bread. Cook for a further 10 minutes - It's nice to get a little char on the bottom of the bread - so don't worry!
