Sandwiches

I'm not really usually fussed about ham but I've recently discovered Aldi's 'Torchon ham' and f33ck me the stuff is lovely on a sandwich with a bit of salad, pepper and a touch of mayo

I plan to go to one of the places mentioned in the crusty cob thread this week and see if I can pick up any deli meats in the process

This brings me to the question... what is your 'go to' sandwich for work/in general?
