Brie, Bacon & Branston Pickle (not sure if you can get the Branston pickle in the US though, but maybe substitute with caramelised onions)
To be honest, I'm not sure if this would work as a piza, but I think it would. I used to make a toasted sandwich with these ingredients and it was awesome. The deep cheesy depth of the brie, nicely molten, plus the saltiness and general bacon-ness of the pig slices, held together with the sweet spicy fruitiness of the Branston.
I'm going to try this at the weekend!
