Make the crab paste: mix the ingredients
together in a bowl and season, then set aside.
In a separate bowl, mix the white meat with
the herbs, lemon juice, oil and seasoning.
Spread the bread lightly with butter, then
spoon and spread the crab paste over 4
of the slices. Pile the white meat over, then
top with the remaining bread. Cut the crusts
off, if you like, and serve halved or in small
triangles or squares with lemon wedges on
