The strong flavors of cauliflower, garlic, red-pepper flakes, and Parmesan cheese balance perfectly, raising these common, readily available ingredients to new heights.
Substitute broccoli for the cauliflower.
Add a handful each of raisins and pine nuts at the same time as the garlic, parsley, and red-pepper flakes.
Use four chopped anchovy fillets instead of the anchovy paste.
Red wine, if it's simple and crisp, makes an intriguing choice for this dish. A touch of earthiness, such as you'll find in a basic Chianti, helps to tie the wine and food flavors together.
