Ingredients
- 2 cans (5–6 oz each) tuna, preferably tuna packed in olive oil (drained lightly)
- 3 tablespoons extra-virgin olive oil (plus more to taste)
- 2 tablespoons fresh lemon juice (about 1 lemon), plus zest of 1/2 lemon
- 1 small shallot or 1/4 red onion, finely minced
- 1 small cucumber, diced (Persian or English preferred)
- 1 cup cherry tomatoes, halved or quartered
- 1/3 cup Kalamata olives, pitted and chopped
- 2 tablespoons capers, drained
- 1/3 cup flat-leaf parsley, chopped
- 2 tablespoons fresh dill or basil, chopped (optional but recommended)
- 1 small garlic clove, grated or very finely minced
- 1/4 teaspoon red pepper flakes (optional)
- Kosher salt and freshly ground black pepper, to taste
- Optional add-ins: 1/2 cup chickpeas (rinsed and drained), 1/4 cup crumbled feta, 1/4 cup chopped roasted red peppers
- To serve: mixed greens, cooked grains (like farro or quinoa), toasted bread, or pita
How to Make It

- Make the dressing: In a large bowl, whisk together olive oil, lemon juice, lemon zest, garlic, red pepper flakes, a big pinch of salt, and a few grinds of pepper. Taste and adjust with more lemon or oil as needed.
- Prep the mix-ins: Add the minced shallot, cucumber, tomatoes, olives, and capers to the bowl.
Toss gently to coat everything with the dressing.
- Add the tuna: Flake the drained tuna into the bowl in large chunks. Avoid over-mixing so it stays pleasantly chunky.
- Herb it up: Fold in parsley and dill (or basil). Taste again and season with more salt, pepper, or lemon to balance the flavors.
- Optional add-ins: If using chickpeas, feta, or roasted red peppers, fold them in now.
Drizzle with a touch more olive oil if the salad looks dry.
- Serve: Spoon over greens, pack into pita, pile on toast, or serve with crackers. It’s also great over warm grains for a more filling bowl.
How to Store
- Refrigerator: Store in an airtight container for 2–3 days. The flavors deepen overnight.
- Keep it crisp: If you want maximum crunch, add tomatoes and cucumber just before serving, or keep them in a separate container.
- Refreshing leftovers: Before serving again, stir in a splash of olive oil and a squeeze of lemon to brighten it up.

Why This is Good for You
- Healthy fats: Olive oil provides heart-friendly monounsaturated fats and antioxidants.
- Lean protein: Tuna offers high-quality protein to keep you full and support muscle health.
- Fiber and micronutrients: Veggies and optional chickpeas add fiber, vitamins, and minerals.
- Lower sugar, lower heaviness: With no mayo and no added sugar, it’s light but still satisfying.
- Mediterranean pattern: This style of eating is linked to better heart health and longevity.
Common Mistakes to Avoid
- Using low-quality olive oil: The flavor is front and center, so choose a fresh, decent extra-virgin olive oil.
- Skipping acid: Lemon juice and zest wake up the salad.
Without them, it can taste flat.
- Overmixing the tuna: Keep some chunks for better texture. Stir gently.
- Salting too early: Tomatoes and cucumbers release water. Taste at the end and adjust seasoning then.
- Not draining ingredients: Drain tuna, olives, and capers well to avoid a watery salad.
Alternatives
- Tuna types: Use solid light or chunk light for a softer texture, or albacore for firmer, meatier chunks.
- Fish swap: Try canned salmon, mackerel, or sardines for a richer flavor and more omega-3s.
- Greens base: Serve over arugula, baby spinach, or chopped romaine for extra crunch.
- Dressing twist: Add a teaspoon of Dijon mustard, a splash of red wine vinegar, or a pinch of oregano.
- Veggie swaps: Sub artichoke hearts, roasted peppers, or thin-sliced fennel for variety.
- Dairy-free or dairy-full: Skip the feta for dairy-free, or add it for a creamy, salty bite.
- Low-carb or grainy: Keep it light with greens, or make it heartier with farro, couscous, or quinoa.
FAQ
Can I use tuna in water instead of oil?
Yes.
Tuna in water works fine. Just add an extra tablespoon of olive oil to keep the salad moist and flavorful.
How do I keep the salad from getting watery?
Drain tuna, olives, and capers well, and seed your tomatoes if they’re very juicy. Add salt at the end, and refresh with a little oil and lemon before serving leftovers.
What if I don’t like raw onion?
Use minced shallot for a milder bite, or soak red onion in cold water for 10 minutes to soften it.
You can also skip it and add more herbs.
Is this good for meal prep?
Absolutely. It keeps well for 2–3 days. Store the salad and greens separately, and assemble just before eating.
Can I make it without garlic?
Yes.
The salad is still bright and flavorful with lemon, herbs, and olives. If you want a hint of garlic flavor, rub the mixing bowl with a cut garlic clove.
What can I serve it with?
It’s great with toasted sourdough, warm pita, crisp lettuce cups, or simple grains. Add a side of sliced cucumbers or a handful of olives for a quick plate.
