This Mediterranean tuna salad is a refreshing and healthy dish that combines the vibrant flavors of the Mediterranean. Perfect for a quick lunch or a light dinner, this salad is packed with protein and fresh vegetables, making it both nutritious and delicious.
If you don't usually have tuna or olives in your pantry, you might need to pick them up at the supermarket.

How to Store or Freeze This Tuna Salad
- Ensure the tuna salad is completely cooled before storing. This helps maintain its freshness and prevents condensation, which can make the salad soggy.
- Transfer the Mediterranean tuna salad into an airtight container. This will help preserve the flavors and keep the salad from absorbing other odors in the fridge.
- Store the container in the refrigerator. The salad will stay fresh for up to 3 days.
- If you plan to freeze the tuna salad, it's best to omit the cherry tomatoes and cucumber as they don't freeze well and can become mushy upon thawing. Instead, add these fresh when you're ready to serve.
- For freezing, place the tuna mixture (without the tomatoes and cucumber) in a freezer-safe container or a heavy-duty freezer bag. Squeeze out as much air as possible to prevent freezer burn.
- Label the container or bag with the date so you can keep track of its freshness. The tuna salad can be frozen for up to 1 month.
- When ready to use, thaw the tuna salad in the refrigerator overnight. Once thawed, add fresh cherry tomatoes and cucumber before serving.
- Always give the salad a good stir after thawing and before serving to redistribute the olive oil and lemon juice dressing evenly.
How to Reheat Leftovers
- Gently reheat the tuna salad in a skillet over low heat. Add a splash of olive oil to prevent sticking and maintain moisture. Stir occasionally until warmed through, but be careful not to overcook the tuna.
- Use a microwave-safe dish to reheat the salad in the microwave. Cover the dish with a microwave-safe lid or microwave-safe plastic wrap. Heat on medium power for 1-2 minutes, stirring halfway through to ensure even heating.
- For a quick and easy method, place the tuna salad in an oven-safe dish and cover with aluminum foil. Warm in a preheated oven at 300°F (150°C) for about 10-15 minutes, or until heated through.
- If you prefer a cold salad, simply let the Mediterranean tuna salad sit at room temperature for about 15-20 minutes before serving. This allows the flavors to meld and the salad to lose its chill without needing to be reheated.
