Prep. Mix together everything except the fish and the olives with a fork. Flake the fish and mix it in. Gently add the sliced olives so they don’t break apart.
Serve. Taste and add whatever you think is needed.
Notes
About the smoked fish. I have done this with salmon and white fish. Works for both. The link above is to a smoked salmon recipe but you could substitute another fish if you wish.
