    Fresh and bold, this Mediterranean Tuna Salad Recipe brings a healthy batch of flavor and zero mayonnaise to your favorite lunchtime sandwich.

    Finding a mayo-free tuna salad recipe that still offers delicious flavor can be challenging. Well no more, friends! With just a couple of cans of tuna (preferably in olive oil!) and a handful of fresh herbs and tasty add-ins, your classic tuna salad gets a huge upgrade.

    Serve it low carb with lettuce wraps or serve it in a bowl with crunchy veggies for dipping. Or go all out with the Ciabatta and Provolone Tuna Melt included below.

    Ingredients for recipe laid out on counter and labeled

    Before we get to the step by step directions, a few notes about the ingredients.

    Tuna: tinned tuna in olive oil is my preference, but use what you have. If that's light tuna in water, plan to taste and adjust seasoning as you may need more salt.

    ​Onion: red onions bring a bit of sweetness to the sharp onion energy. But use yellow onions, sweet onions or even diced green onions instead. 

    Olives: An Italian olive like Castelvetrano is perfect, but good old Spanish olives work well, too. Substitute with capers, pickled peppers or even dill pickles.

    Garlic: Fresh is best, but substitute a pinch of garlic powder, if you must. 

    Vinegar: Substitute fresh lemon juice or white wine vinegar, if you prefer. 

    Herbs: fresh basil and flat leaf parsley (or Italian parsley) are the perfect pair. Substitute fresh dill, fresh chives or fresh tarragon. 

    Full ingredient list and measurements included in the printable recipe card below.

    Step by step instructions:

    1. Make mustardy vinaigrette

    Combine 2 tablespoons of the olive oil drained from your tuna (or two tablespoons extra virgin olive oil), with red wine vinegar, the grated garlic clove and a good pinch of salt and freshly cracked black pepper. Whisk to combine. 

    oil, vinegar, spices and mustard mixed in a bowl

    Add thin-sliced red onion and stir. Set aside to marinate while you assemble the salad.

    2. Toss together tuna salad

    Combine chopped olives, diced basil, parsley and drained tuna in a bowl. Toss to mix.

    Pour dressing over the mix and toss again. Taste and adjust seasoning. The tuna salad is ready to serve in bread, on crackers or over a salad!

    3. To Make Mediterranean Tuna Melt

    Slice open a ciabatta roll and add a slice of provolone to each side. Lay a small piece of parchment in between and close the sandwich.

    Preheat a skillet over medium-high heat. Once hot, add a drizzle of olive oil to the pan, then lay the closed sandwich in the skillet. Use a second skillet to weight the sandwich.

    Grill for 2-3 minutes, until golden brown. Remove weight and flip sandwich. Return the second skillet as weight and grill for another 2-3 minutes.

    Remove the sandwich and open, discarding the sheet of parchment. Add Mediterranean tuna salad to the bread. Close and cut in half to serve warm.

    FAQ's and Serving Suggestions:

    Can I use water-packed tuna in this recipe?

    You can! It doesn't bring the richness and flavor of fish tinned in olive oil, so plan to add a bit more salt and pepper to the final tuna fish dish.

    What can I add to canned tuna besides mayo?

    I'm partial to this Mediterranean herb and Dijon dressing instead of tuna. But if you're looking for a healthier alternative to creamy mayo, try greek yogurt with fresh herbs instead!

    What can I do with canned tuna besides tuna salad?

    Smoky Tuna Dip and Tuna Empanadas are two of my favorite recipes to make with this pantry staple! And I also open a can of tuna over this Mediterranean Tossed Salad at least twice a month for a quick and healthy lunch. 

    How to store leftover healthy tuna salad?

    Store leftover Mediterranean Tuna Salad in an airtight container in the refrigerator for up to 4 days.

      I assume that the mustard goes in the salad dressing?

          This is a wonderful recipe! I made it to serve with rosemary crackers as an appetizer for our New Year’s Eve soup dinner party. It was a bit hit, even with guests who are not fans of tuna salad. I plan to make the tuna melt sandwiches for our lunch today. Thanks Christina for another great recipe! Happy New Year!
