Cold Roast Beef Sandwich is a delicious and easy meal consisting of sliced baguettes loaded with layers of creamy mayonnaise, arugula, truffle oil, thinly sliced roast beef, shaved Parmesan, and chopped nuts.
Combine the mayonnaise and truffle oil until thoroughly mixed. In a pan over medium-high heat, roast the pine nuts for approximately 3-4 minutes, or until they turn golden brown on the outside.
Slice the baguette and spread the truffle mayonnaise evenly on the top and bottom bun.
Layer the arugula on the baguette. Add the slices of roast beef. Sprinkle shaved parmesan on top.
Season with salt and pepper.
Finish by garnishing with roasted pine nuts. Cut the sandwich in half and savor the flavors.
