Drain the canned tuna thoroughly and transfer it to a large mixing bowl. Use a fork to gently flake it into chunky pieces. Avoid over-mixing so the tuna keeps some satisfying texture.
Add the diced cucumber, halved cherry tomatoes, chopped Kalamata olives, red onion, roasted red peppers, and crumbled feta cheese to the bowl with the tuna.
In a small bowl or jar, whisk together the extra virgin olive oil, fresh lemon juice, red wine vinegar, minced garlic, dried oregano, salt, and black pepper until fully combined.
Pour the dressing over the tuna and vegetables. Add the fresh parsley and mint, then gently fold everything together until evenly coated. Taste and adjust salt, pepper, or lemon juice as needed.
Serve immediately over crisp romaine lettuce, stuffed into pita bread, or scooped onto toasted sourdough. Alternatively, refrigerate for up to 30 minutes before serving to let the flavors meld.
One of the things that makes this Mediterranean tuna salad recipe so practical is how many ways you can serve it. A few ideas to get you thinking:
Want to switch things up? Try adding capers, sun-dried tomatoes, artichoke hearts, or white beans. All of these are classic Mediterranean ingredients that work beautifully with tuna.
This salad is best enjoyed fresh, but it holds up well in the fridge for up to 2 days in an airtight container. If you are planning ahead, store the dressing separately and toss just before eating to keep everything crisp and vibrant.
This is one of those Mediterranean diet tuna recipes that actually tastes even better the next day once the flavors have had time to develop. The lemon and oregano really bloom overnight. Just give it a good stir and a fresh squeeze of citrus before serving.
