[pen] I used to get my lunchtime panino/i in a food court in Dublin, cooked by Italians. They had a choice of 4 each day, and were various combinations of parma ham, bresaola, aubergine, olives, mozzarella, basil, pesto, sundried tomato etc. Always delicious, and great with a large espresso.

[Phil] If I was feeling mean, I'd point out that you may have just described immigrants selling a bastardised version of what Dubliners might consider foreign food. But I'm not. I'm just hungry. It's the last of the proper British pork chops tonight (ie more than 4mm thick), when the windy miller finally gets home.

Anything that doesn't involve potatoes and/or coleslaw counts as foreign food in Ireland :-)
The reason I asked in the first place is that I have a "Panini Grill" which does great toasted sandwiches, but I want to take advantage of the lunchtime panini market. My personal preference for fillings seems to be miles away from what other people want/expect, for which information I'm very grateful.

[Phil] I'd suggest going round a few of your local coffee shops just before lunch time and see what they have most of on their shelves. You can be sure they've done the research. The only difference about your trade is that you could probably go a little dryer and saltier.
Mind you this definitely sounds like 'teaching your grandmother'.

[INJ] This assumes that supply = demand. There are at least two canteens that I've encountered that would run out of certain things very quickly on a daily basis and never increase their order of those things. You could even ask 'Do you have any more X?' and they would say 'No, they always sell out really quickly'...
