We generally have fairly full food cupboards, because we do a big supermarket shop once every 3-4 weeks, then stock up on fresh food at the market every week.
We usually have the following store cupboard food:
Pasta, rice
Tinned tomatoes
Baked beans (though I'm the only one who likes them!)
Crisps
Biscuits
Sugar, flour, icing sugar, corn flour
Marmite
Jam
Dried stuffing
Cereals
Pasta sauce
Balti curry sauce
I'm wondering what else we could get? Most of our meals are mainly fresh meat and veg with pasta or rice. But if there's an Event which stops us getting fresh food we're going to get pretty bored of our food! (don't have a huge freezer either)
I've bought a couple of tins of peas and ravioli (which makes DH 
cos we don't eat them generally). The only tinned fruit I like is prunes and they don't sell them here
