How can I dress up canned tuna without mayonnaise?

Oil and (mostly) vinegar dressing?

Garlic and dill sounds good. :)

Use an old fashioned oil, balsamic vinegar and some dijon mustard vinaigrette with a little dill or tarragon.

That’s essentially mayo without the egg yolk.

Personally I would never marry tuna salad with garlic.

Any salad dressing you have. Check your herb and spice choices and see if any appeal when combined with the scent of tuna. Cheese?

Do you have an avocado? That works pretty well, and it’s the ‘good’ kind of fat.

You could also try using low-fat salad dressing.

The oils in the tuna are all you need. Add celery, black pepper, and dill (if you like)

There was a time I hated Mayo and used djonaise in it inplace of mayo, it had the creamy texture of mayo with out the fat and calories of mayo.

Mmm, mustard for sure.

@creative1: Out of curiosity I just checked the ingredients in dijonaise;

WATER, VINEGAR, MUSTARD SEED, SOYBEAN OIL*, MODIFIED CORN STARCH, SALT, SUGAR, EGG WHITES, XANTHAN GUM, COLOR ADDED, NATURAL FLAVOR, SPICE, (SODIUM BENZOATE, CALCIUM DISODIUM EDTA) USED TO PROTECT QUALITY, PAPRIKA, WHITE WINE, CITRIC ACID, YELLOW 5, TARTARIC ACID, PAPRIKA OLEORESIN, TURMERIC .

If nothing else, you lost me with the dye YELLOW 5.

Thank you, all. These are great ideas. I’m off to the kitchen to prepare dinner.

Mix it in with Kraft Dinner.

Wasabe, or horseradish is good with tuna.

Just use a teaspoon or so of lite, or non-fat mayo ( about 40 calories, no big whoop ) and mix in a spoonful of sweet pickle relish for extra moisture and flavor.
Delicious!
If you are staying away from breads stuff your tuna salad in celery stalks or a big, juicy tomato slightly hollowed out, or spoon it onto a handful of lite crackers like low fat wheat thins.

Don’t forget shrimp too. I eat tons of shrimp in salads or dipped in a little cocktail sauce.

Drain the tuna juice into a small bowl. Add soda crackers to the juice and crush them with a fork until they make a paste. Add lemon juice to make the crackers creamier. Add the tuna and add capers (if you like them), chopped celery and/or sweet relish to taste. Makes a great tuna salad and the crackers extend the tuna at the same time. No mayo at all!

Make a green salad and then flake the drained tuna on top.

Plain yogurt, dill.

Greek style yogurt

Sweet chilli sauce goes great with tuna!

Three suggestions:
1.) Don’t drain out all of the liquid, and substitute mustard instead of mayo.
2.) Chopped up celery, carrots, pickles, peppers, hard boiled eggs or just the whites, or any vegetables that sound appealing and are on hand can can be added.
3.) Pasta with tuna and a bunch of vegetables, plus tomatoes, tossed with a bit of salad dressing is fantastic.

Oooh sweet chili sauce. The Trader Joes brand is great and drizzling it over lowfat cottage cheese and dipping with rice tortilla chips is a divine snack!

Plain yoghurt sounds nice, or I instantly thought about cottage cheese and you can add some spices to your liking. I like lemon pepper. Yum.

Can you just cut the amount of mayo in half and make it lower fat? After a while I think you will get used to it, and it will become normal. I mash up the tuna really well, then add a little mayo and a sprinkle of salt (and sometimes I add celery to the tuna salad) I put it over crunchy iceberg lettuce, and I add black olives to the iceberg, sometimes shredded carrots (or just use a peeler to peel of thin slices of carrot). My husband like carrots, tomatoes and cucumbers in his salad, plus a little salt. Then squeeze a lot of lemon or lime on the whole thing. It’s delicious.

@Coloma FYI: shrimp has quite a bit of cholesterol if you watch that.

I like it with lemon juice, pepper, and chilli flakes. I like mayo but not with tuna. And I like it served in a half avocado. We often have that for dinner. Fresh tuna is the best but good quality canned is good too.
