Instructions
- Step 1: In a small bowl, whisk together the Dijon mustard, lime zest, and lime juice. Add the olive oil, sumac, salt, pepper, and crushed red pepper flakes if using. Whisk until the vinaigrette is well blended, then set aside briefly.
- Step 2: In a large salad bowl, combine the tuna with the chopped celery, cucumber, radishes, green onions, red onion, Kalamata olives, parsley, and mint. Mix gently with a wooden spoon to combine evenly.
- Step 3: Pour the prepared vinaigrette over the tuna salad. Toss gently to coat all ingredients evenly with the dressing.

Tips & Variations
- For extra crunch, add chopped toasted almonds or pine nuts just before serving.
- Swap Kalamata olives for green olives if you prefer a milder flavor.
- Use fresh lime juice instead of bottled for the best zesty flavor.
- Omit the crushed red pepper flakes or adjust to taste for a milder salad.
- Serve the salad over mixed greens or with warm pita bread for a fuller meal.
Storage
Store the salad in an airtight container in the refrigerator for up to 2 days. The flavors will continue to develop but the fresh herbs and vegetables are best enjoyed within this time. When ready to eat, give it a gentle toss and serve chilled. Avoid freezing, as the texture of the vegetables and tuna may change.
How to Serve

Serve this delicious recipe with your favorite sides.
FAQs
Can I use fresh tuna instead of canned tuna?
Yes, but you would need to cook and cool the fresh tuna before adding it to the salad. Canned tuna provides convenience and a consistent texture, making the recipe quick and easy.
What is sumac and can I skip it?
Sumac is a tangy, lemony spice commonly used in Mediterranean cooking. If unavailable, you can omit it or substitute with a small squeeze of lemon juice or a pinch of lemon zest to maintain brightness in the dish.
