Mediterranean tuna salad

We’re always looking for fast lunch and easy dinner ideas: and this one works for both. Introducing Mediterranean Tuna Salad! Combine canned tuna with crunchy vegetables, feta cheese, olive oil and a punch of Dijon mustard for the most flavorful salad to hit your plate! Serve it with crackers as an easy lunch, or over greens for a quick dinner with pita bread and olives. This one is so quick and versatile, it’s in our hall of fame of healthy meal ideas. Here’s how to make this tasty Mediterranean diet recipe.

Ingredients for Mediterranean tuna salad

This Mediterranean tuna salad combines quick and easy canned tuna with Mediterranean flavors: cool cucumber, briny caper, salty feta and tangy Dijon mustard. It’s pretty straightforward in its composition, but it’s a genius idea for using simple ingredients to make big flavors. We made it once, and it’s now on repeat for a simple lunch or dinner. Here’s what you’ll need:

  • Canned tuna:  Use either water-packed or oil packed (we prefer water packed).
  • Shallot: A milder version of red onion, it’s a favorite for salads.
  • Red bell pepper
  • English cucumber: This variety is long and thin with no tough skin, no seeds and a milder flavor than standard cucumber: look for it in the produce section!
  • Capers: These bring big salty, briny flavor: look for them jarred near the pickles in your grocery
  • White wine vinegar
  • Olive oil
  • Dijon mustard
  • Kosher salt
  • Feta cheese crumbles, optional

All you have to do for this recipe: flake the tuna, chop the veggies, and mix it together! It’s seriously simple and the pop of tangy, savory flavor is unreal.

Canned tuna nutrition

Canned tuna is part of a healthy diet! Even better, it’s shelf stable for 2 to 5 years in your pantry. It’s a pretty amazing ingredient. Here’s what Healthline has to say about the nutritional benefits:

  • Canned tuna is high in protein and low in calories. One 5-ounce can of tuna has about 30 grams of protein, which is about 60% of your daily need.
  • Tuna is a good source of Omega 3 fatty acids that contribute to brain and heart health.
  • Look for tuna that is sustainable and low in mercury. Find cans of light or skipjack tuna, and sure they have an MSC certification on the label.

  1. This was so delicious and I didn’t even have all of the ingredients! I was out of dijon mustard so just omitted that, replaced the capers with finely chopped green olives and added a little lemon juice to the dressing. Served with whole grain crispbreads for a delish lunch!!! Love that it’s super easy and nutritious :)

  2. This is really easy to make and taste great the next day for lunch at work. Had to keep my husbands hands off of it.

  3. This is bussin and i would eat it during every meal for the rest of my life I don’t have much time since I have prostate cancer. Thank you for the meal that I will be enjoying for the rest of my short, short life ahead.

  4. Wow! This was so good! Lots of crunch from the fresh vegetables with a lingering dijon and vinegar seasoning; not overloaded with the flavor of tuna. We will be making this one again.

  5. This was amazing! I didn’t have white wine vinegar so I used rice vinegar and it was incredible. I ate this with pita chips and it made the perfect lunch. I will definitely be making this again and again!
