For the love of trying to do everything myself (and the necessity of not having very much money), I ventured into cracker territory about a month ago.
What resulted was delicious, pretty easy, and lasted for a long time (three weeks in an airtight container).
My favorite part is the crackers were a blank slate for whatever I wanted to sprinkle on top -- from sesame, flax and poppy seeds, to parmesan, rosemary and garlic.
