Browsing through my iPhone's wine apps - of which I probably have far too many - I checked with one called Wine Steward, which is also available online, to find out what they advise as a pairing with tuna salad.
Grenache gets a 100% vote of confidence from Wine Steward and is branded as an "excellent pairing." Grenache makes versatile, fruity wines. Great rosés are made from Grenache grapes, and that would be my choice for the tuna salad.
Sauvignon Blanc gets 80%. If you feel the need to pair a white wine with fish, this is a great choice.
Sancerre, at 79%, comes from France's Loire Valley. A Sancerre would probably be a Sauvignon Blanc as well, as that is the grape predominantly used in Sancerre.
Chardonnay gets 71%. A big California Chardonnay may have the mark of oak in it, while a less buttery flavor will come from France, like a white Burgundy or Chablis.
A host of other wines are mentioned by Wine Steward, in declining order:
Nero d'Avola, a big red wine from Southern Italy
Rosé
Riesling
Cabernet Sauvignon
Dry Gewürztraminer
Sangiovese
Syrah
Merlot
Red Bordeaux
Sparkling Wine
Cabernet Franc
Viognier
Beaujolais Cru
Roussanne
Pinot Gris
Off-Dry Gewürztraminer
Albariño
Carignane
Pinot Noir
Zinfandel
Of this last bunch - mostly labeled as "adventurous" choices by the app - I'd go with a Roussanne, a full-bodied and food-friendly white wine with a nice high acidity.
