This Mediterranean Tuna Salad is about to become your new lunch obsession!

I’m not even kidding. The first time I made this, I ate it three days in a row. And I regret nothing!

Plus? It comes together in 15 minutes flat. No cooking, no fuss, just fresh, vibrant flavors that’ll make you feel like you’re eating lunch on a Greek island.

Ready to fall in love with tuna salad all over again? Let’s go!

Why This Recipe is a Total Game-Changer

This isn’t your grandma’s mayo-heavy tuna salad. Not even close!

This one’s bright, fresh, and packed with Mediterranean flavors. Think: sun-dried tomatoes, Kalamata olives, crisp cucumber, and creamy feta.

The secret? A simple lemon-olive oil dressing that lets all those gorgeous ingredients shine. No mayo needed!

I love making this for meal prep. It actually gets BETTER after a day in the fridge. The flavors meld together, and everything just… clicks.

It’s perfect for those days when you want something healthy but don’t want to feel like you’re eating rabbit food. Because life’s too short for boring salads, right?

The Ingredient Line-Up

Let’s talk about what makes this salad so ridiculously good.

The Tuna: Here’s where quality matters. I use solid white albacore tuna packed in olive oil. The oil-packed variety stays tender and adds richness. Water-packed works too—just drizzle in some good olive oil!

The Vegetables: Cucumber adds crunch. Tomatoes bring sweetness and juiciness. Red onion gives a sharp bite (soak it in ice water first if you want to mellow the flavor!).

The Olives: Kalamata olives are my go-to. They’re fruity, briny, and SO flavorful. But honestly? Use whatever olives make your heart happy.

The Feta: Oh, that tangy, salty, creamy feta! It pulls everything together. Don’t skip it unless you absolutely have to.

The Dressing: Just lemon juice, olive oil, oregano, salt, and pepper. Simple, bright, perfect.

Pro tip: If you can find jarred roasted red peppers, throw some in! They add a subtle smokiness that’s chef’s kiss.

How This Beauty Comes Together

Okay, here’s where I get really excited. Because this is SO EASY.

First, make your dressing. Whisk together olive oil, lemon juice, oregano, salt, and pepper. Set it aside so the flavors can get friendly.

Now the fun part: chop all your veggies. I like everything bite-sized and uniform—makes it easier to eat and prettier to look at!

Toss your vegetables with the dressing first. This gives them a head start on soaking up all that lemony goodness.

Then—and this is KEY—gently fold in the tuna, beans, and feta last. You want nice chunky pieces of tuna, not a mushy mess. Treat it gently!

That’s it. Seriously. You just made restaurant-quality lunch in your own kitchen. High five!

My Favorite Ways to Serve It

This salad is ridiculously versatile.

Stuff it in a pita pocket with some crispy lettuce. Pile it on toasted sourdough. Scoop it up with crackers for an easy appetizer.

My personal favorite? On a big bed of mixed greens with extra lemon wedges on the side. Light, fresh, and somehow fancy-feeling even though it took 15 minutes.

For meal prep, I pack it in mason jars with the dressing on the bottom. Shake before eating. Boom—instant healthy lunch!

Storage Tips That Actually Work

Good news: this salad keeps beautifully!

Store it in an airtight container in the fridge for up to 4 days. The flavors actually IMPROVE overnight as everything marinates together.

Just give it a quick stir before serving to redistribute the dressing.

Make-ahead hack: Chop your veggies and make your dressing the night before. In the morning, it takes 5 minutes to throw everything together. Future you will be SO grateful.

Your Questions Answered

Can I use a different type of tuna?

Absolutely! Chunk light tuna works great. Even canned salmon would be delicious here.

Is this salad gluten-free?

Yes! The salad itself is naturally gluten-free. Just watch what you serve it with.

Can I make it dairy-free?

Skip the feta or use a dairy-free alternative. Add some avocado for creaminess!

How do I keep the red onion from being too strong?

Soak your sliced onions in ice water for 5-10 minutes before chopping. Game changer!

Calories: 245

Ingredients
  

For the Salad:
  • 2 (5 oz) cans solid white albacore tuna in olive oil, drained
  • 1 English cucumber, quartered lengthwise and sliced
  • 1 pint cherry tomatoes, halved
  • ½ red onion, finely diced
  • 1 (15 oz) can cannellini beans, rinsed and drained
  • ½ cup Kalamata olives, pitted and halved
  • ⅓ cup crumbled feta cheese
  • ¼ cup fresh parsley, chopped
For the Dressing:
  • ¼ cup extra virgin olive oil
  • 2 tablespoons fresh lemon juice
  • 1 tablespoon red wine vinegar
  • 1 teaspoon dried oregano
  • ½ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • 1 clove garlic, minced

Equipment

  • Large mixing bowl
  • Small bowl or jar for dressing
  • Whisk or fork
  • Sharp knife and cutting board
  • Can opener
  • Measuring cups and spoons

Method
 

  1. Make the dressing: In a small bowl or jar, whisk together olive oil, lemon juice, red wine vinegar, oregano, salt, pepper, and minced garlic. Set aside to let flavors blend.
  2. Prep the vegetables: If using red onion, soak sliced pieces in ice water for 5 minutes to mellow the flavor, then dice. Quarter the cucumber lengthwise, then slice into bite-sized pieces. Halve the cherry tomatoes and roughly chop the parsley.
  3. Combine vegetables: In a large bowl, add cucumber, tomatoes, red onion, and parsley. Pour the dressing over and toss until well coated.
  4. Add protein and cheese: Drain the tuna and cannellini beans. Gently fold in the tuna (keeping it in chunky pieces), beans, olives, and feta cheese. Toss gently to combine without breaking up the tuna too much.
  5. Serve: Enjoy immediately, or refrigerate for up to 4 days. Give it a quick stir before serving to redistribute the dressing.

Notes

  • Tuna Options: Solid white albacore in olive oil is best, but chunk light tuna or tuna in water works too. If using water-packed, add an extra tablespoon of olive oil to the dressing.
  • Bean Swaps: Chickpeas, black beans, or white navy beans all work great in place of cannellini beans.
  • Add More Veggies: Roasted red peppers, artichoke hearts, diced bell peppers, or sun-dried tomatoes are excellent additions.
  • Meal Prep Friendly: This salad keeps for 4 days in the fridge and actually improves in flavor as it sits.
  • Serving Suggestions: Serve on a bed of greens, stuffed in pita bread, scooped onto crackers, or piled on toasted sourdough.
