Hilton Potatoes

There are, obviously, people all over the world like ourselves who cook potatoes in this way but I have a problem with the naming of this dish. It is a sort of ratatouille, but without the long cooking time; it is also an excellent way of conjuring a vegetarian dish out of almost nothing and can be adapted to what is available in the kitchen. The only basic requirements are potatoes and tinned tomatoes and who would ever be without those?
