Lately I am a big fan of wraps - grated cheese, avocado, tomato, whatever salad stuff you have. I usually like meat / chicken, etc on sanwiches, but with wraps it doesn't seem to matter! The wraps keep fresh longer than bread and I tape up the bags to make sure they don't go dry.

Also good are microwaved potatoes with cheese, tomato paste, coleslaw and a dob of sour cream or greek yoghurt on top.

There was something else I had in mind when answering, but DD has interrupted and I have forgotten - will repost when I remember!
