What Makes This Special

Step-by-Step Instructions

1. Make the dressing. In a small bowl, whisk together olive oil, lemon juice, lemon zest, Dijon, garlic, oregano, a pinch of salt, and pepper.

   Taste and adjust—add more lemon for brightness or more oil for a softer finish.

2. Prep the vegetables. Halve the tomatoes, dice the cucumber, slice the onion thin, and chop the roasted red pepper if using. Rinse capers and slice olives.
3. Flake the tuna. Drain well and gently break it apart with a fork. Keep some larger chunks for texture.
4. Combine the base. In a large bowl, add tuna, tomatoes, cucumber, onion, olives, capers, and roasted red pepper.

   Sprinkle in parsley and any mint or basil.

5. Dress it. Pour the dressing over the salad and toss gently. You want everything coated but not crushed.
6. Add feta. Fold in feta at the end so it stays a bit chunky. Taste and adjust salt, pepper, and lemon.
7. Serve your way. Spoon over greens, tuck into pita, or serve with toasted bread.

   For a heartier meal, add beans or toss with cooked grains or small pasta.

8. Let it rest (optional). If you have 10–15 minutes, let the salad sit so flavors meld. It gets even better after a short rest.

Storage Instructions

• Refrigeration: Store in an airtight container for up to 3 days.
• Keep greens separate: If serving with lettuce or arugula, store them separately to avoid wilting.
• Revive before serving: Stir and add a splash of olive oil and lemon to brighten leftovers.
• Avoid freezing: The vegetables won’t hold their texture when thawed.

Health Benefits

• Lean protein: Tuna offers high-quality protein to keep you full and support muscle health.
• Healthy fats: Extra-virgin olive oil and tuna provide omega-3s and monounsaturated fats that support heart health.
• Fiber and antioxidants: Vegetables, olives, and optional beans bring fiber, vitamins, and polyphenols.
• Lower in mayo: Using a lemon-olive oil dressing cuts heavy calories while keeping it satisfying.
• Balanced meal: Add whole grains for complex carbs, or keep it low-carb with leafy greens.

Common Mistakes to Avoid

• Using low-quality tuna: Choose solid or chunk tuna packed in olive oil for best flavor and texture. If using tuna in water, add a touch more olive oil.
• Overdressing: Start with less dressing and add as needed.

  You can always add more, but you can’t take it away.

• Skipping the rinse on capers/olives: Rinse briefly to control saltiness and balance the salad.
• Overmixing: Gentle tossing keeps the tuna chunky and the vegetables crisp.
• Forgetting acidity: Lemon is key. If the salad tastes flat, a squeeze of lemon fixes it fast.

Recipe Variations

• Beany boost: Add chickpeas or cannellini beans for extra fiber and creaminess.
• Green-forward: Toss with arugula, baby spinach, or chopped romaine for a bigger salad.
• Grain bowl: Serve over quinoa, farro, or orzo. Drizzle with extra olive oil and lemon.
• No-dairy: Skip the feta and add avocado or toasted pine nuts for richness.
• Spice it up: Add a pinch of red pepper flakes or a spoonful of harissa to the dressing.
• Herb swap: Use dill and chives instead of parsley and mint for a different vibe.
• Roasted twist: Add roasted cherry tomatoes or charred peppers for depth.

FAQ

Can I use fresh tuna instead of canned?

Yes.

Sear a tuna steak to medium-rare, cool, and flake it. Season lightly with salt and pepper before mixing. It will taste cleaner and more delicate.

What kind of tuna is best?

Solid or chunk light tuna in olive oil gives great flavor and texture.

Albacore works too but can be drier; add an extra teaspoon of olive oil if needed.

How can I make this ahead for meal prep?

Mix everything except the greens and feta. Store the dressing separately or lightly dress the salad to avoid sogginess. Add greens and feta just before serving.

Is there a good substitute for olives?

Try chopped artichoke hearts, sun-dried tomatoes, or extra capers for briny depth.

You can also add a few sliced cornichons for tang.

What if I don’t like raw onion?

Soak sliced onion in cold water for 10 minutes to mellow the bite. Or use thinly sliced scallions or shallot for a gentler flavor.

Can I make it without garlic?

Absolutely. Skip the garlic and add a pinch more mustard and lemon zest for flavor.

A small grating of shallot also works.

How do I keep the cucumbers from watering down the salad?

Use Persian or English cucumbers and pat them dry after chopping. If using standard cucumbers, scrape out the seeds before dicing.

What if it turns out too salty?

Add more tomatoes, cucumber, or a handful of cooked grains to dilute the saltiness. A squeeze of lemon also helps balance the flavors.
