Tuna fish salad gets a Mediterranean lift from charred zucchini, kalamata olives, and a shower of fresh mint and parsley. Canned tuna, avocado, and tomato round out the bowl, all glossed with olive oil and balsamic. It is a five-minute assembly that eats like a proper lunch.
Ingredients
- 10 kalamata olives, pitted (1.4 oz / 40g)
- 1 small zucchini, sliced lengthwise (4 oz / 113g)
- 0.5 medium avocado, diced (2.5 oz / 70g)
- 2 cups mixed greens (1.5 oz / 42g)
- 1 large tomato, diced (6.4 oz / 182g)
- 1 green onion, sliced (0.5 oz / 15g)
- 1 can chunk light tuna in water, drained (5 oz / 142g)
- 0.25 cup fresh parsley, chopped (0.2 oz / 5g)
- 0.5 cup fresh mint, chopped (0.4 oz / 11g)
- 1 tbsp. extra virgin olive oil (0.5 oz / 14g)
- 1 tbsp. balsamic vinegar (0.5 oz / 14g)
- 0.25 tsp. fine sea salt (0.05 oz / 1.5g)
- 0.75 tsp. black pepper, cracked (0.06 oz / 1.7g)
Step-by-Step Directions
- Grill the zucchini slices on each side for a few minutes until tender and lightly charred, then cut them into bite-size pieces once cooked.
- Grab a large bowl and combine the grilled zucchini, drained tuna, diced avocado, tomatoes, mixed greens, olives, green onion, parsley, and mint.
- Drizzle the extra virgin olive oil and balsamic vinegar over the mixture, add the fine sea salt and cracked black pepper, and gently toss all the ingredients together.
- Serve your Tuna Fish Salad immediately while still fresh, as this dish tastes best right after preparation and is not ideal for leftovers.

Pro Tips
- Drain the Tuna Thoroughly: To prevent a soggy salad and keep the flavors concentrated, make sure you press out as much water as possible from the canned tuna before mixing it with your greens.
- Master the Zucchini Char: Ensure your grill or pan is very hot before adding the zucchini slices. This sears the outside quickly, giving you beautiful grill marks and a smoky flavor without turning the vegetable to mush.
- Keep the Avocado Fresh: Dice your avocado right at the very end just before tossing the salad. This prevents oxidation and keeps the vibrant green color intact for your final presentation.
- Customize the Acid: Balsamic vinegar provides a fantastic sweet and tangy depth, but if you want a brighter, more traditional Mediterranean flavor profile, swap it out for fresh, freshly squeezed lemon juice.
Frequently Asked Questions (FAQ)
Can I meal prep or make this Tuna Fish Salad ahead of time? Because this recipe features delicate mixed greens, fresh tomatoes, and avocado, it is best enjoyed immediately. If you need to prep in advance, store the wet ingredients (tuna, tomatoes, dressing) in a separate airtight container from the greens and avocado, and combine them right before serving to maintain the perfect crunch.
What type of canned tuna is best for a healthy salad? Chunk light tuna in water is excellent for a flaky texture and absorbs the dressing beautifully. If you prefer larger, firmer pieces of fish, opt for solid white albacore. Tuna packed in olive oil is also a great choice if you want richer flavor—just be mindful of the added fats.
How can I modify this salad for a stricter low-carb lifestyle? While this salad is packed with whole foods, you can easily reduce the total carbohydrate count by halving the amount of diced tomato and swapping the balsamic vinegar for a zero-sugar acid like lemon juice or raw apple cider vinegar.
What can I add for extra crunch? If you want to elevate the texture of your Tuna Fish Salad, try tossing in a handful of toasted pine nuts, pumpkin seeds, or some finely diced celery and cucumber.
Pro Tips
- Get the grill or pan very hot before the zucchini goes in — a fast sear gives smoky char marks instead of limp, waterlogged slices.
- Press as much water as possible out of the canned tuna before mixing; a soggy base dilutes the olive oil and balsamic dressing.
- Dice the avocado at the very last moment and toss it gently so the pieces stay green and intact.
- Swap the balsamic for fresh lemon juice if you prefer a brighter, more traditional Mediterranean profile — the rest of the salad needs no changes.
- This one is carb-heavier than most keto plates at 37.5g per serving, so split it into smaller portions or skip the tomato on strict keto days.
Frequently Asked Questions
Can I make tuna fish salad ahead?
Grill the zucchini and mix everything except the avocado up to a day ahead. Add the avocado and dressing just before serving so nothing wilts.
What can I use instead of mixed greens?
Shredded romaine or baby spinach both hold up under the warm zucchini and tuna without going limp.
Is this salad keto-friendly?
It is higher-carb at 37.5g per serving because of the tomato and zucchini; portion it smaller or drop the tomato to fit a strict keto day.
Can I use fresh tuna instead of canned?
Seared fresh tuna chunks work beautifully — cook them rare, chill, and fold them in place of the canned tuna.
