Rinse the salt of the fish very well (2 or 3 times). You can also soak overnight or for a few hours. I usually rinse the fish very well, then boil it to remove the excess salt. Sporadically taste the fish to make sure it’s to your liking.
Let it cool and rinse with cold water.
In a large bowl, mix the chopped avocados, chopped onion, chopped tomatoes, olive oil, vinegar, and lemon juice.
Pull the fish into flakes and make sure there are no stray bones.
Add the fish to the bowl with the rest of the ingredients and mix very well.
Add pepper to taste and salt if needed. The fish might still have some remaining salt.
Serve immediately and ENJOY!
