Pasta with cauliflower, walnuts and feta

I love this recipe. I make it with a few modifications: I use a red onion, pine nuts instead of walnuts, and queso fresco instead of feta. It's delicious. The whole wheat pasta really stands up to the cauliflower.

An Alice Waters recipe.

This is a very unusual combination of ingredients, but it works perfectly. The cauliflower is sauteed over a high heat which makes it very crunchy and lovely.

Do make it exactly as prescribed, at least the first time, because the details really matter here.
