From My Carolina Kitchen
Left over slices of rare roast beef from a prime rib
1 slender French baguette
Black truffle butter, at room temperature
Fleur de sel French sea salt and freshly ground black pepper to taste
Fresh Parmesan cheese
Fresh baby arugula
Bring left-over roast beef slices to room temperature. Cut the baguette lengthwise, but not all the way through. Spread the bottom half of the bread generously with the black truffle butter. Top with a layer of sliced beef and sprinkle it with the fleur de sel and freshly ground black pepper. Using a vegetable peeler, shave the Parmesan cheese into thin shards and scatter the shards over the sliced beef on each sandwich. Sprinkle with arugula leaves, fold the tops of the sandwich over, and cut into diagonals.
