Honest to god advice... get some student recipe books.
Packed with easy, cheap and tasty recipes. I have two from my uni days and cook from them all the time.
They aren't too expensive either, unlike some of the grand recipe books you see with ingredients and cooking methods you've never heard of.
Saying that though, I used to find Sainsbury's recipe site quite good, haven't look in a while though so don't know what recipes are on there at the moment:
