To throw in my 2 cents: it's the wrong time of the year to start a garden, and I'm guessing you won't have a yard to plant one in, but-- have you looked to see if there are any community gardens around? Come spring, you could get some space in one, and in the meantime, they might have some "help yourself" beds. Not much help over the winter, but growing your own is a great way to get cheap, high-quality produce.
