Yes, there are some good things on the site, but I still can't see that 30p per head per meal over a whole day/week would be possible. The main meals would need some veg or salad to go with them, so they'd be more than a £1.
Yes, I do spend £22 a week on food Casdon, but that doesn't include washing up liquid or fuel to cook and I have a friend with a huge allotment who provides me with veg for the most of the year. I freeze what I can, so I always have something for veg curry or soup.
It seriously pains me when I see dishes on menus for the amount I spend in a whole week.
It doesn't help that I don't eat high carb food, but I honestly don't think I could eat any more frugally.
