Broccoli rabe, also known as rapini, is a delicious slightly bitter green that has nothing to do w/ broccoli. Rapini seems to be making its appearance in grocery stores now. I bought some at Harris Teeter last night. Go buy some.
Here's how to fix it:
Wash and chop it up. Heat a tablespoon or two of olive oil in a skillet over medium. Add some chopped garlic (however much you like) and a pinch of red pepper flakes. Add the rapini and saute over medium heat until it is tender. Season w/ salt and pepper.
This is a good side dish or you can mix it w/ cooked pasta topped with grated parmesan cheese. You could also pour 4 cups of chicken stock over the cooked greens, add a can of canellini beans or great northern beans, cook until beans are warmed through. Top w/ parmesan cheese and croutons made from toasted day-old bread (pain paysan from Guglhupf comes to mind).
