Pasta (whatever kind you like, however much you think you can eat)
Garlic (however much you like)
Salt and pepper
Put a pot of water on to boil and cook pasta according to package directions. Or just cook it according to the way you know how, I'm sure you're not a moron. While it's cooking, you're going to zest the lemon. I know this sounds like kind of a big deal but it's really not. Either get out a cheese grater, stick it over a bowl, and rub the lemon against the side with the smallest holes in it like this
or just peel the lemon with a veg peeler or knife and then cut it up into tiny little pieces. Sorry to be a nuisance but they really should be tiny or you'll get a mouthful of peel which is gross.
Now put a bit of olive oil in the pan and then add a sizable chunk of butter. Use more butter than oil but you do need the oil unless you seriously think you can cook this thing on crazily low heat, watch it like someone's paying you, and still not get pissed off when it burns and you have to do it again. Once the butter is melted, press the garlic into it (if you have a garlic press, if not just chop it up small and toss it in there) and cook until it smells nice, then add the lemon zest, a bit of salt and pepper, and cooked pasta (should be done by now), then stir. Cut the lemon that you zested in half and squeeze the juice from both halves into the pan and stir again.
That's it. You're done. I'll admit that that pasta dish with just olive oil and garlic might be a little easier than this but while some may call that cuisine I personally would call it bullshit.
