Roast the pig yourself with a state of the art Hog Master Hog Roast machine.
Just lay the pig (or Lamb or your selection of meats) into the roasting tray, close the lids, switch the gas on low and let your meat cook whilst you get on and enjoy preparing your other food.
6 hours later (for a pig) open up the doors, probe the meat to check it's at the correct temperature, switch the machine off, place on serving hooks and then carve at your leisure.
