Husband;
pasta
tofu

dairy free choc
canned chick peas

We used to have a big organic garden but husband got tired of it, so giving it a rest.
I do think its a good idea to have some junk food, myself. I have a weakness for chips so only buy small bags -as soon as a I open them, I eat the whole bag.
I eat the most boring meals! Mostly steamed veggies and a baked potato. Im sick of cooking.

On that note, for cheap student cooking - how about a crock pot? You often can get one from thrift shops. I had a rice steamer when I was young and poor - but dont mistake barley for rice( bought ten lbs - yuck!).
You should( whomever that was) eat more fruit and veggie. Lots of people are coming down with scurvy, believe it or not( my Mother in law for one) now days. At least two fruits and three serves of veggies will keep bad things away( food stamps will help, I went thru that too.Its nice to be able to afford food!!)
