With crunchy vegetables, fresh herbs, and a zesty Dijon dressing, this no-mayo Mediterranean tuna salad is loaded with flavor and nutrition. Once you try it, you will never go back to those heavy deli-style tuna salads!

Mediterranean Tuna Salad with fresh herbs, chopped vegetables and Dijon vinaigrette on a plate

Unlike classic tuna salad, this recipe is completely mayo-free and it takes on a delicious Mediterranean twist, thanks to loads of crunchy veggies, fresh herbs, and a bright Dijon dressing with lime juice and good extra virgin olive oil.

I often make this healthy tuna salad stuffed in pita pockets for the perfect sandwich night. But you can also serve it as an appetizer with pita chips or over sliced tomatoes for a lower-carb option.

What kind of tuna to use?

Tuna on its own can be a wonderful protein option. It is also nutrition rich, containing B-6, B12, vitamin A, iron, zinc, magnesium, potassium and omega-3 fatty acids.

There are a couple kinds of tuna out there, white albacore and chunk light. Some packed in olive oil, and some packed in water.

I turn to responsibly caught Albacore which is higher in heart-healthy omega-3 fats. And if you’re concerned about the fat content, your best bet will be tuna packed in water. I’ve used both in the past, but I do prefer to add my own extra virgin olive oil so I can control the flavor and the amount used. I like Early Harvest Greek olive oil with tuna, it is rich and has a good peppery finish.

Mercury levels in tuna can be a health concern, which is why my family consumes tuna no more than once every two weeks. (Talk to your healthcare provider if you have concerns about eating canned tuna)

Ingredient notes for this recipe

  • Tuna. You’ll need 2 to 3 cans of quality tuna, packed in water. I use responsibly-caught Albacore tuna (look for the dolphin-safe label).
  • Vegetables and Herbs. Cucumbers, celery, radish, onions, parsley and min, chopped into small bits will add crunch and great fresh flavor!
  • Olives, Capers, or Pickles. Pitted and sliced kalamata olives or a handful of drained capers will add a nice briny and slightly salty flavor to this tuna salad recipe. This is a very Mediterranean thing to do, and if you’re not a fan of olives or capers, you can chop up some pickles instead.

Tuna salad dressing

For the perfect tuna salad without mayonese, I make a zesty Dijon dressing using:

Tuna salad ingredients in a mixing bowl

Tuna salad instructions

  • Make the dressing by whisking the Dijon mustard with the lime juice, olive oil, salt and pepper, sumac, and red pepper flakes (if you like a bit of heat). By the way, you can make the dressing a day or two in advance and keep it in the fridge in a tight-lid mason jar.
  • Drain and add the tuna to a large bowl.
  • Add in the remaining ingredients including chopped celery, English cucumber, radish, green onions, and red onions. Add in the olives (or capers).
  • Pour the dressing all over the tuna and mix well.

Leftovers and Prepare-Ahead Instructions

This Mediterranean tuna salad will keep well in the fridge, stored in tight-lid glass container, for about 2 days or so.

If you’re looking to try and make it ahead, you can make the dressing a day or 2 ahead of time and save it in the fridge in a tightly closed mason jar. You can also chop the vegetables and fresh herbs etc. and store them in the fridge in separate zip-top bags. When you are ready to serve, add the tuna and chopped items in one large mixing bowl and combine with the dressing.
