Brie & Grape is a type of sandwich I heard Snotty Ollies buy a lot of from Marks & Spencer (a lower middle-class department store-cum-supermarket in Britain)
Cheese & Pickle however, is a nasty concotion that British oiks & riff-raff scoff a lot of. The most popular make of pickle for the sarnie is Branstons, which, the last time I looked, had everything it it from cauliflower to cat shit.
