Me and the missus were reading something about how much food gets wasted, and one of the suggestions for how to reduce it was planning out your meals for, say a week, then only buying the stuff for those meals – instead of just stocking up on whatever takes your fancy then trying to use it all before it goes off.
Well we have done it for the last week and it's been really successful. Not only in terms of not wasting stuff but we have eaten a really nice, healthy, interesting selection of stuff this week – because of taking the time to think about it in advance not when you are hungry and knackered after work.
I know it sounds desperately boring and middle-aged, but if the result is spending less money and eating nicer, healthier food then it's all good with me. Maybe lots of people do this already, I dunno?
