Fusilli & Roasted Cauliflower with Capers from Melissa Clark's Dinner p 190.
This recipe adds a spoonful of butter, along with garlic, lemon zest and juice and zest, toasted pine nuts and grated cheese. The butter contrasts nicely with the sharpness of the lemon and capers - half of which get roasted along with the cauliflower.
Nice variation on something I usually make without a recipe.
