Penne with garlic and broccoli rabe

This recipe is straight from Smitten Kitchen. It's incredibly easy to throw together: a box of penne (or other shape), a head of broccoli rabe, a few cloves of garlic, a half cup of olive oil, seasonings, parmesan cheese.

Reprinted below:

1 pound pasta, whatever shape you like (but chunky ones will match up better with the rabe)
1 pound broccoli rabe, heavy stems removed, remaining stems and leaves cut into 1- to 2-inch sections
1/2 cup olive oil
5 garlic cloves, peeled and minced or pressed
1/2 teaspoon red pepper flakes, or more or less to taste
About 1 heaping teaspoon Kosher salt (or more to taste)
To serve: Grated Parmesan or Romano cheese

 Bring a huge pot of salted water to a boil. Add pasta and five minutes before its cooking time is up, add the broccoli rabe. It will seem like too much for the water, but with a stir or two, the rabe should wilt and cook alongside the pasta. Drain rabe and pasta together and pour into serving bowl. In the same pot or a tiny one, heat the olive oil with the garlic, pepper flakes and Kosher salt over moderate heat, stirring frequently for 3 to 4 minutes, or until the garlic becomes lightly golden. Pour mixture over pasta and toss to evenly coat. Shower with freshly grated cheese and eat at once.
