Have you tried Hellman's Dijonnaise? It's a Dijon mustard-mayo combo that's only 15 calories per tablespoon. I think it works really well with tuna.

Vegenaise is DELICIOUS!

I like Nasoya fat free vegan mayonnaise, 10 cals per tbsp. Also plain lowfat yogurt works well at 7 cals per tbsp.

For flavor, I add dijon mustard, basil, lemon juice, and a dash of cayenne pepper.

You don't have to eat mayo if you don't like it. Why not use a olive oil and vinegar dressing on your tuna instead?

Good point Zenor. Avacado also mixes well with tuna.

I understand where you are coming from. I have always used Helmans (real mayo) but since I have switched to the reduced fat one I have found that if I add a little salt to it, I don't miss the real mayo taste as much.

My husband likes to use Hidden Valley Ranch Light (not fat free) instead of mayo. I usually use half regular Hellman's and half fat free sour cream, or I also like homemade or bottled light italian or vinaigrette dressing.

I don't really care much for mayo but I bought some for a recipe. I bought Nayonaise which is pretty good (kind of like miracle whip) and fairly low calorie.

I think most reduced fat and fat free mayos are hideous, so I prefer to use smaller amounts of the "good stuff," and then dilute with skim milk, fat free sourcream (which I do like), rice wine vinegar, dijon mustard, horseradish, or even water.

Try cottage cheese, and I've seen recipes for tuna salad that use tomato paste or pasta sauce, if that appeals

I couldn't agree more!

I also use pepperoncinis in my tuna salad and use some of the juice to make it more 'wet' if you know what I mean...

What about miracle whip light/ Fat Free?

*raises hand for Nasoya mayo!!!*

I love that stuff. I much prefer it to all of the other mayo substitutes... the others are often too salty or tangy.
