This is to be made with the way old time toasts used to be made when we did not have toasters,by frying in the pan remember?
So fry some slices of prosciutto. Then add one side buttered slice of white bread in the pan. On top of the slice add some Brie pieces. Then put the prosciutto on top of the cheese. Add another buttered bread slice to the pan let it get golden brown. Cover the other slice on top of the prosciutto and Brie and press it down with a ladle.
