Macaroni Salad with Tuna Fish

 My Grama V, whose real name was Charlotte, made the most delictable macaroni salads for every family event of my childhood. Later I asked her for the recipe and she told me, and everyone else that asked, the same thing, "I'll take my macaroni salad recipe to the grave with me" and eventually she did.

After years of searching, this is the closest recipe no closer than the Ranch version of Suddenly Salad with a can of tuna tossed in. Maybe that was the secret she was protecting?
