Place a cast iron gratin dish on the bars, close the BBQ and allow it to heat.
Add the oil, and once it starts to shimmer add the peppers.
Close the BBQ so they get really hot.
Check and turn the peppers from time to time.
Once the peppers have started to blister add the chorizo, stir and allow to cook for a few minutes.
Finally top with the mixed cheese. Allow the cheese to melt and to bubble and brown around the edges.
Liberally season with salt.
