Mediterranean Tuna Salad

Last summer, my neighbor Maria brought over a bowl of this tuna salad after I'd mentioned feeling too exhausted to cook. She'd just returned from visiting family in a small coastal town in Greece, and she swore this was the closest thing to the lunches they'd eat on her aunt's terrace overlooking the Aegean. One bite and I completely understood why Mediterranean cuisine has such a devoted following. Now it's my go-to when I want something that feels special but requires zero actual cooking.

I started making this for weekly meal prep after realizing it actually tastes better after the flavors have had time to marry. My partner now requests it every Sunday, and we've developed a little ritual of eating it on our balcony while watching the sunset. Something about those bright vegetables and briny olives just makes everything feel lighter and more manageable.

Ingredients

• Tuna in olive oil: Trust me on this, the oil packed tuna makes such a difference in flavor and moisture compared to water packed
• Cherry tomatoes: They burst with sweetness and hold their shape better than larger tomatoes when tossed
• English cucumber: Fewer seeds and a more tender skin than regular cucumbers, plus they stay crunchier longer
• Red onion: The sweetness balances beautifully with the briny olives and tangy feta
• Kalamata olives: These add that authentic Mediterranean punch you cannot substitute
• Fresh parsley and basil: Dont skip the herbs, they make the whole salad taste bright and alive
• Lemon juice: Fresh is absolutely essential here, bottled just does not cut it
• Feta cheese: Even if you think you do not like feta, try it here, it adds the perfect creamy salty element

Instructions

Prep your fresh vegetables:

Take your time halving those cherry tomatoes and dicing the cucumber into neat, bite sized pieces, the knife work is meditative and the prettier everything looks, the more you will enjoy eating it

Combine the base vegetables:

In your largest salad bowl, toss together the tomatoes, cucumber, sliced red onion, diced bell pepper, and those gorgeous halved Kalamata olives

Add the tuna:

Gently flake the drained tuna into the bowl, trying not to break it up too much so you still get satisfying chunks in every bite

Whisk together the dressing:

In a small bowl, whisk the olive oil, red wine vinegar, fresh lemon juice, Dijon mustard, minced garlic, dried oregano, salt and pepper until the mixture thickens slightly

Dress and toss:

Pour that vibrant dressing over the salad and use salad hands or two spoons to gently fold everything together until every piece is lightly coated

Add the finishing touches:

Fold in the chopped fresh parsley and basil, then scatter the crumbled feta over the top like edible confetti

Last month, I brought this to a potluck and watched three different people ask for the recipe. There is something about the combination of textures and flavors that just works perfectly on a warm day. It has become the dish I associate with good company and easy conversation.

Making It Your Own

Sometimes I add diced celery for extra crunch or throw in capers when I want even more brine. My sister likes to add diced avocado, which turns it into something almost creamier and more substantial. The base recipe is forgiving enough to handle whatever you have on hand.

Serving Suggestions

This shines when served over a bed of mixed greens or tucked inside a whole wheat pita for a portable lunch. I have also served it alongside roasted vegetables for a more complete dinner feeling. It is versatile enough to work however you need it to.

Make Ahead Strategy

You can prep all the vegetables and whisk the dressing up to a day in advance, just keep them separate until ready to serve. I have found the tuna actually benefits from marinating in the dressing for about 30 minutes before serving. The salad holds up beautifully for lunch the next day, though the vegetables will soften slightly.

• Store any leftovers in an airtight container and eat within 2 days
• If taking to work, pack the dressing separately and toss right before eating
• The flavors actually develop beautifully after sitting for a few hours in the refrigerator

This is the kind of recipe that reminds me why simple, fresh ingredients are often the most satisfying. Hope it brings a little sunshine to your table too.
