This recipe rebuilds the salad, reimagining it as crostini: Parmesan and dressed escarole (in place of romaine) are piled on top of white anchovies, which are cured in vinegar and oil and have a mild flavor.
If you don't have pumpkin-pie spice, you can instead use 2 teaspoons ground cinnamon mixed with 1/4 teaspoon each of ground ginger and nutmeg. It's very important to make sure the bread soaks up the flavorful custard to ensure a velvety consistency.
Prepare yourself for a few rousing verses of "For She's a Jolly Good Fellow," sung by the vegetarians in your group. Far from a limp and wilted also-ran or meatless mystery, this sandwich packs brightness (chickpeas gently mashed with lemon juice, lemon zest, and olive oil) as well as a mix of textures from the cheese, eggs, and fennel shavings.
