if you live in a college dorm do you need to make all your meals or do you get some of them in the cafe? also what other "supplies" would you need?
if you are looking at just dinner or lunch i would go with pb&j and the ramen noodles. also look for soups going on sale, and of course campbells has coupons frequently. chicken nuggets come in big bags but can be squeezed into small spaces so could fit in your freezer then you could have occassional meat. you could also still do spaghetti sauce. i freeze my extras in ziploc bags and if you lay them flat they dont take up tons of room.
i will be thinking of other things for you
