Line another cookie sheet with foil or parchment. In a food processor, using the pulse button, process the bread, olive oil, garlic, basil, parsley, salt, pepper and nutmeg, until you get coarse crumbs. Place them on the second cookie sheet. Place both sheets in the oven, using upper third rack for the crumbs, and lower third rack for the cauliflower. Bake about 25 minutes, checking a couple times on the sheets. The crumbs might be ready first. The cauliflower should be nice and dark. In a platter, toss the pasta with the cauliflower, the reserved pasta cooking liquid, the crumbs mixture and the added oil, and serve hot.
