lol my flatmate just opens up a can on tuna when he is hungry, drains out the water and grabs his fork lol.... it is so funny, sometimes it looks like he is eating a tin of cat food or something.
Toast is another great thing, especially if you freeze your bread because then you don't waste any due to mould.
But to get scurvy you would have to be pretty stupid or really really poor. 39 c for noodles, like buy an orange instead every now and then. If you have enough money to buy noodles you have enough money to buy some sort of fruit or veg every once in a while.
On the subject of noodles, is anyone a big fan of the Mi Goreng indonesian ones they sell? They are quite deluxe for noodles, and only 45 c (sometimes 39 c if there is a special) very bad for you though lol.
