Melt the butter in the olvie oil in a large skillet.
Add the broccoli rabe with the water that clings to
it, season with salt and pepper and stir to coat.
Cover and cook over high heat for 1 minute. Stir the
broccoli rabe and reduce the heat to moderate. Cover
and cook until crisp-tender, about 3 minutes. Season
with salt and pepper, sprinkle with the grated
Parmesan cheese and serve. Source Food & Wine April
