Cut out the backbone, flatten it out, marinate in:

olive oil
ketchup (not 2 much or the sugar will burn up)
paprika (lots of)
pepper
garlick
chicken salt / regular salt
butter
anything else you fancy (parlsey, oregano, rosemary, lemon zest)

Slow cook over indirect heat for an hour or so like everyone else here has alluded to.

The beercan method rocks too. A real crowd pleaser - I once did 6 at once.
