Halve the avocado and remove the seed. Widen the hole in the center so that it's large enough to snugly fit a poached egg. Carefully remove the rind from the avocado with a spoon.
Spread a sheet of cling film over a small bowl and crack open the egg over the film, being careful not to break the yolk. Draw the cling film together and close with a twisty tie or a bag clip. Cook the cling film baggie in simmering water for 5 minutes.
Carefully peel the poached egg and place it in one half of the avocado, then cover it with the other half. Wrap the two halves together with slices of bacon, fully covering the exposed avocado flesh.
Brown the bacon on all sides in a frying pan with just a touch of oil to keep it from sticking.
