Check out this menu madness, from a Californian restaurant:
They don't go in a lot for cheese toasties here, which I put down to a paucity of Brevilles. But they do go in for a 'grilled cheese' which by the way is really not grilled. It's made on a griddle, or in a frying pan. Which in my family makes it a 'cheese dream'. I know. P is quite confused. If offered a 'grilled cheese' she refuses, but if I say 'it's a cheese dream' she's suddenly interested. I just have to explain that the difference between grilled cheese and a cheese dream is the same as the difference between a cookie and a biscuit. That is to say, it just depends whether you are in Hermosa Beach or in Granny's house.
Now here's a sandwich I can never explain: the Monte Cristo. In it's simplest form it's a cheese dream, or a Croque Monsieur. A fried cheese sandwich. But then often here they dip it in egg before frying it. I'm good with that. And yet sometimes, are in the land where anything is possible, it includes ham and turkey, and is made with a sweet bread (like cinnamon raisin), and served with powdered sugar, and suddenly I don't know if I'm eating a sandwich or a cake, breakfast or dessert.
As we say in England, just because you can, doesn't mean you should.
