This Sicilian-style salad is more heavily dressed than other green salads, so that there's extra oil and vinegar to soak up with bread.
Cooks' notes:
•If your sea salt is very granular and pebblelike, crush it using the flat side of a large heavy knife or the bottom of a heavy skillet.
•Greens can be washed and torn 1 day ahead and chilled in sealed plastic bags lined with dampened paper towels.
