Preparation

Start by thoroughly washing the Tropea onions, then peel and slice them thinly, aiming for even slices. Place the onion slices in a bowl and to tone down their sharpness, let them soak in cold water for about 10 minutes, then drain. Meanwhile, wash the salad greens under running water and dry them using a salad spinner or by gently patting with a clean kitchen towel. In a large salad bowl, combine the salad greens, sliced onions, drained and flaked tuna, and halved cherry tomatoes. Add pitted black olives and gently mix to combine the ingredients without breaking them. Drizzle with extra virgin olive oil to taste, a splash of white wine vinegar, salt, and pepper, adjusting to your preference. Toss again to evenly distribute the dressing and let the salad rest for a few minutes before serving to allow the flavors to meld.

Tips
If you prefer a milder flavor, you can use white onions instead of red ones. For a vegan version, replace the tuna with legumes like chickpeas or beans. The salad keeps well in the fridge for 1-2 days, but it's best enjoyed fresh to appreciate the flavors.
Trivia
Red onions are particularly prized for their sweet flavor and crunchiness. In Italy, they are often used in salads and fresh dishes, especially during the summer. Canned tuna, on the other hand, is a versatile food that has become popular due to its convenience and long shelf life, making this dish accessible to everyone. Finally, white wine vinegar is a traditional condiment that can vary from region to region, with different types of grapes used for its production.

Benefits of Tropea Onions in Onion and Tuna Salad

Can Onion and Tuna Salad be stored in the refrigerator?

It is possible to store Onion and Tuna Salad in the refrigerator, but it is important to do so correctly to preserve freshness and flavor. After preparing the salad, place it in an airtight container and consume it within 1-2 days to avoid the onions becoming too pungent and losing their crunch. If you want to keep it even fresher, you can store the ingredients separately and combine them only at the time of serving. This precaution is particularly useful if you have added cherry tomatoes, which tend to release water and can make the salad watery. Remember to mix well before serving, to redistribute the flavors and make the dish appetizing again.
