Wash and dry lettuce. Rinse berries, remove stems and cut in half.
For dressing, blend together sugar, onion, paprika and Worcestershire sauce in a jar. Gradually add oil and vinegar in a steady stream until blended. Stir in sesame and poppy seeds.
To serve, arrange lettuce and berries on chilled serving plates. Drizzle dressing over top. Serves 6 to 8.
Note: May also toss lettuce with dressing before adding berries.
