Mediterranean Tuna Salad Recipe FAQs

What’s the best type of tuna to use for Mediterranean Tuna Salad?
I always recommend tuna packed in olive oil for extra richness and flavor. It keeps the salad moist and adds a lovely depth compared to tuna in water. Look for solid or chunk light tuna for a pleasant texture.

How ripe should the tomatoes be for this salad?
Choose firm, ripe tomatoes that are just beginning to soften but still hold their shape. Overripe tomatoes with dark spots can make the salad watery, while underripe ones won’t give that juicy burst you’re craving.

Can I store leftover Mediterranean Tuna Salad? If so, how long will it last?
Absolutely! Store leftover salad in an airtight container in the fridge for up to 3 days. To keep veggies crisp and fresh, I suggest adding the dressing just before serving if you anticipate leftovers.

Is it okay to freeze Mediterranean Tuna Salad?
Freezing the entire salad isn’t ideal because fresh veggies lose their texture, but you can freeze the tuna separately for up to 3 months. When ready, thaw the tuna in the refrigerator overnight, then toss it with freshly chopped veggies and dressing.

What if I have a garlic allergy or want a milder flavor?
No worries! You can simply leave out the garlic or substitute it with a pinch of garlic powder or a small amount of shallots. The dressing will still have plenty of zesty, lemony brightness to shine through.

Can this salad be made vegan or vegetarian?
For a vegetarian or vegan twist, skip the tuna and increase the olives or add chickpeas for protein. Crisp veggies and the vibrant dressing still deliver all the Mediterranean freshness without compromise!
