If using a BBQ plate as opposed to a grill, allow the plate to heat and sprinkle a coat of salt covering the plate. Allow the salt to brown before adding oil and onion. Cook until onion is browning and scrape the plate clean. This process will allow you to place meat on the BBQ without the meat sticking to the plate. Simple but effective and anyone can do it.
I love it, so simple to prepare and easy to cook.
Sounds delicious, will try it over Xmas, even though it seems a bit time-consuming to prepare.
