Shrimp Salad Tea Sandwiches

In a medium bowl, combine shrimp, parsley, lemon juice, zest, Worcestershire, and mayonnaise. Stir to thoroughly combine; season with salt and pepper.

Thinly spread butter on two bread slices. Cover one with shrimp salad and sprouts, if using; top with other bread slice. Use a serrated knife to trim crusts and cut into two triangles; cut in half again to make four small triangles. Repeat with remaining ingredients. Cover with damp paper towels until ready to serve.
