I made this last night with kale instead of frisee. It was a big hit with my two teenage boys and husband. The only thing I would recommend is to DOUBLE the recipe if you are feeding teens. DELICIOUS!
I didn't know what Frisee was either. So I looked it up on Worldwide Gourmet:
An edible plant with long, wide leaves in shades of green or sometimes red, or simply edged with red. As its name suggests, frisn n e is a curly lettuce whose long tender leaves are joined to a short whitish stem which somewhat resembles the base of the fennel plant.
So basically, it's a fancy head of lettuce.
