The garlic-nut sauce known as tarator, which sometimes also includes tahini, is a classic Turkish accompaniment to mussels and fried fish as well as vegetables. Here, it's used with cauliflower that is sliced — rather than separated into florets — so that it can be more easily browned, which gives it a nutty flavor that complements the tarator perfectly.
Cooks' note:
Toast nuts in a shallow baking pan in a 350°F oven until golden, 5 to 10 minutes.
