While most Caesars drown the greens in a heavy dressing, this lemony version lets the taste of the shrimp shine through. Don't worry about the anchovies - they'll mellow in the dressing, giving it a rich taste that can't be duplicated.
Make Ahead Tip: The dressing (Step 1) will keep, in a jar in the refrigerator, for up to 3 days. Shake vigorously just before tossing with the salad.
