On holiday in Portugal we had the most DIVINE tuna toasties - they had onion, tomato and mayonnaise in too - served hot of course. They didn't look at all like the toasted sandwiches we do here in sandwich toasters, as the edges weren't sealed. Does anyone know of a special sandwich toaster which will do this - its obviously made in a machine as it had the diagonal grill marks on the outside of the toast and olive oil too - very yummy, I now get withdrawal symptoms for them!
