My plan for the new year is to spend no more than £2 on lunch every day. Any ideas what I can eat? (I'm ruling out home-made sandwiches 'cos I live alone and it means you have the same thing for days in order to use up whatever you bought).

Today I had a tuna light lunch. It was quite nice. Not all that substantial but I do need to start shedding xmas pounds so that might not be a bad thing.
