I know you asked for food cupboard
ideas but do you have a freezer? I always think there are lots of things that you can freeze or buy frozen that you could stow away in the freezer to make meals with your store cupboard stuff.
So you could freeze odds and ends of bread, grated cheese, any leftovers from meals.
If you are able.to take advantage of big packs of meat - assuming you eat it - then split down and freeze or take advantage of reductions
Buy

I always keep a pack of sausages and bacon as well.
Iceland is really good for stuff like this - loads of offers - you obvious need the space to freeze but I can often get a week out of stuff I stow away with my store cupboard basics and a few fresh items
