Simple Barbecued Asparagus Recipe

First, light the barbecue and get it ready for cooking. Put the asparagus spears in a shallow dish or bowl and drizzle over the olive oil. Season well with the salt and pepper and gently tumble them with your hands to ensure all the spears are evenly coated. When the barbecue is ready, place the asparagus on the hot grill and cook for about three minutes, using tongs to turn the spears regularly so that they cook evenly. When the asparagus is bright green and has nice char marks all over, transfer it to a serving plate; drizzle over the lemon zest and a little more olive oil, then scatter over the lemon zest and use a potato peeler to shave over some parmesan. Serve straight away.
