I love a spreadsheet and I love being frugal so this is excellent!
I do set myself a food budget of £150 a month which could deffo be reduced If I got into a better habit of cooking more
I do love a store cupboard dinner though, some of the best ones come from the "'F'All Left In" pre dinner rant ha ha
Haha, I love a spreadsheet, too! I wanted something that was easy to keep tabs on and provides enough evidence for health professionals. It's lots of fun trying this sort of thing now and then, each time I retain a few extra good habits.
