Scoop the avocado flesh onto a board or plate, chop (but do not mash), slice and then quickly do a chopping action over the seafood sticks so that it shreds a bit (I mean, if you can be bothered, you can just slice and be done with it).
Now start mixing the seafood sticks with the avocado flesh, adding squeezes of the lime as you go.
Chop and add the coriander, mix well with a gentle chopping action.
Scoop the mix back into the avocado shells and serve.
Note: other ingredients I would try adding to this base, in no particular order, are: chopped feta cheese and freshly chopped red chilli, boiled egg, chopped spring onion, a couple of drops of tabasco. You can also replace the lime with lemon and a touch of smoked paprika goes really well.
