You will need
About 50g white crab meat
Extra virgin olive oil
Fresh herbs of your choice, to garnish
Season the crab meat to your taste with a drop or three of lemon juice, a little salt and olive oil. Carefully peel the avocado and slice it in half horizontally, so that you end up with a top and a bottom. Remove the stone and slice away the base so that the avocado bottom is flat underneath and can stand up on a plate.
Fill the centre of the avocado with crab meat and put the top half of the avocado on the crab meat. Using a pastry brush, paint olive oil on to the avocado and on to the herbs. Stick the herbs on to the side -- the oil should hold them.
