Surprise! I was a broke college student. With no car, no money, and pretty much nothing but a kitchen and two pots, along with maaaaaybe ten dollars a week to spend on food. Granted, this was 1998, so ten dollars went pretty far, but not as far as you would think, given that my lack of car also meant I had to buy most of my groceries at the corner convenience store.
To survive, I came up with this recipe, and it's so delicious, I still make it to this day. It's made almost entirely from non-perishables, save for the onions, which can be omitted if you must, although they're so cheap and so readily available, even in drugstores, that why not?
To me, it's the ultimate cheap comfort food. And as comfort foods go, not too terrible for you. The whole thing costs less than $5 to make, and feeds a flipping army. For me, one batch would go for at least four meals, usually five. You can't beat a filling, reasonably nutritous meal for $1 when you're in college. Or any other time, really.
1 can black pitted olives
1 pound pasta
If you have any herbs or garlic powder or fresh garlic, great. If not? No biggie.
