You don't actually need to have a hangover to enjoy this for breakfast (or anytime), but there is something about this easy and quick dish of eggs cooked in a fiery tomato sauce that just hits the spot when you're in need of morning-after succour.
One of the cheapest meals in existsnce. Nigella Lawson's Eggs in Purgatory. Also healthy, and most cheap food isn't healty. This one is top notch. You can use fresh tomatoes and stew them yourself if you don't like canned veggies.
