Avocado Stuffed with Smoked Fish

The best avocados I have ever eaten were grown on a large tree near Tampa Bay. This area is also noted for its smoked mullet. The two ingredients fit nicely together in a recipe from Ghana, which I have adapted here. Any good smoked fish will do, but those that have been cold-smoked should first be steamed or poached for about 15 minutes, or until they flake easily when tested with a fork.
