Salt and pepper the beef fillet and wrap it in a salami shape using cling film, then freeze. Remove from freezer and, prior to thawing, thinly slice using a slicer and place the beef slices totally covering the serving platter.
Prepare the pesto by mixing all ingredients in a blender, then brush the Carpaccio slices with the sauce obtained. In the platter centre, arrange a bouquet using different types of lettuce and dress with the remaining sauce. Cut Parmigiano Reggiano cheese in petal-shaped slivers and use them to garnish the lettuce bouquet.
