This Mediterranean tuna salad transforms simple pantry staples into a high protein meal ready in 10 minutes! With crunchy vegetables, briny capers, and tangy Dijon mustard, it’s the perfect quick lunch or light dinner that fits into a Mediterranean diet lifestyle.
As busy home cooks, we’re constantly searching for those recipes that require minimal effort and deliver maximum flavor. Here’s one that’s the perfect example: this Mediterranean tuna salad!
The first time we whipped this up, we were surprised at how a few simple ingredients could create something so vibrant and satisfying – crunchy vegetables, briny capers, and tangy Dijon mustard transform ordinary canned tuna into something extraordinary. We love this one scooped onto crackers for a quick desk lunch or served over fresh greens with pita bread and olives for a light summer dinner on the patio.
Tips for this 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. Here’s how to get the best results:
- Choose the right tuna: Water-packed tuna works best for this recipe as it allows the Mediterranean flavors to shine. Look for sustainable options with an MSC certification on the label.
- Don’t skip the shallot: Shallots provide a milder, more complex flavor than regular onions. If you don’t have shallots, red onion will work, but use slightly less.
- Drain capers well: Drain the capers thoroughly before adding them to prevent the salad from becoming too watery.
- Use English cucumber: English cucumbers are ideal for this recipe because they have thinner skin, fewer seeds, and aren’t as watery as regular cucumbers. If using a standard cucumber, peel it and remove the seeds.
- Herb additions: Fresh herbs like dill, parsley, or basil make nice additions if you have them on hand.

Flavor variations
We know many people are cooking for families with varying tastes and dietary needs, so here are some easy ways to customize this Mediterranean tuna salad:
- Greek-inspired: Add chopped Kalamata olives, more feta cheese, and a sprinkle of dried oregano for a distinctly Greek flavor profile.
- Italian twist: Incorporate chopped sun-dried tomatoes, fresh basil, and swap the feta for small mozzarella pearls.
- Spicy version: Add a minced jalapeño, chili crisp, or a pinch of red pepper flakes.
- More substantial: Fold in cooked quinoa or chickpeas to create a heartier meal with extra protein and fiber.
- Vegan alternative: Replace the tuna with a 15-ounce can mashed chickpeas and omit the feta (or use a plant-based feta alternative).
- Avocado: Mix in chunks of ripe avocado just before serving for creamy richness and healthy fats. (Keep in mind, this variation does not store well.)
