Problem: limited supplies, cold night, laziness. Solution: Onion soup!
All you need to do is chop up a bunch of onions. Careful this will cause tears...take off your glasses if you wear 'em, light a candle and bear through it. If none of this works, stick your head in the freezer. Seriously. I didn't believe it work work but it does. I hate that it works. But it does!
Then put the onion slices into a frying pan with a little butter, slat, pepper and whatever else you have on hand that you'd like in your soup. This time around, I threw in a dash of the beer I was drinking, some balsamic vinegar and a little cumin. You need to wilt the onions down a lot. This is called caramelizing your onions. It will seem impossible at first but then, after 15 minutes or so your big batch of onions will caramelize and wilt down into yumminess.
In a pot on the stove, simmer some stock, traditionally beef stock. Add the onions and simmer some more. That's your soup. Simple as can be. Not necessarily the best, fanciest or refined recipe but it works. If you want to French it up, add some bread and cheese on top. Broil for a couple seconds and enjoy. Seriously. It will be tasty. And careful not to get too close to anyone afterwards - it may be KISS soup but its still onion soup!
