A lovely spring salad with a little kick.
Cook pancetta until crispy, place on paper towels until cool then chop. Set small pot of water to boil. Cut asparagus into 1" pieces. Place asparagus into boiling water for three minutes. Strain and rinse with cold water, set aside. If the hazelnuts you purchased are raw, toast them by placing them in a pan on medium heat till they are toasted. Allow to cool and then use fingers to peel off the brown skin. Grate cheese. Place all ingredients on a platter and toss.
