Can anyone recommend any good vegetarian cookbooks for students?

I'm moving to university later this year, and although I already know quite alot of recipes, I will need at least one cookbook to take away for when I need inspiration. I will be on a shoestring budget, and therefore can't use recipes with alot of ingrediants (as I've found that chefs like Deliah Smith use). Can anyone recommend me any good vegetarian cookbooks for someone on a limited budget? I eat alot of vegetables, pasta, beans, pulses, lentils, etc.
