Broccoli may be used steamed or raw.
Steam the broccoli until just tender or leave raw. Cut pear into a small bowl, pour in lemon juice and stir. Cover all surfaces of the pear with lemon juice. Mix vegetables and lemon-soaked pear together in a bowl large enough to hold everything, reserving the lemon juice. In the bowl with the lemon juice slowly whisk in olive oil, vinegar, Worcestershire sauce and pepper. Pour over lettuce and toss. Put shrimp on top.
