Ingredients
- 2 cans (5 oz each) tuna in olive oil, drained
- 2 cans (15 oz each) cannellini beans, rinsed and drained
- 1 cup cherry tomatoes, halved
- 1/2 red onion, finely diced
- 1/2 cup Kalamata olives, sliced
- 1/4 cup fresh parsley, chopped
- 1/4 cup extra-virgin olive oil
- Juice of 2 lemons, about 1/4 cup
- 1 tsp dried oregano
- 1/2 tsp sea salt
- 1/4 tsp freshly ground black pepper
- 1/2 cup crumbled feta (optional)
How to Make Mediterranean Tuna & White Bean Salad
- Whisk the dressing: In a small bowl, whisk together the extra-virgin olive oil, lemon juice, dried oregano, sea salt, and black pepper until lightly emulsified.
- Build the base: In a large serving bowl, combine the rinsed cannellini beans, halved cherry tomatoes, diced red onion, sliced Kalamata olives, and chopped parsley.
- Add the tuna: Break the drained tuna into large flakes and scatter it over the beans and vegetables so every bite gets a little.
- Dress and toss: Pour the lemon-oregano dressing over the salad and toss gently until everything is coated. Taste and adjust the salt, pepper, or lemon juice to your liking.
- Finish and serve: If using feta, sprinkle it over the top. Serve right away — or let the salad rest for 10 minutes so the flavors come together.
Tips for the Best Tuna and White Bean Salad
- Use tuna packed in olive oil, not water. It gives the salad a richer flavor and silkier texture. Drain it lightly, but don’t press it dry — a little of that good oil is pure flavor.
- Rinse the beans well. It washes away excess starch so the dressing clings to every bean instead of turning cloudy.
- Chop the onion finely. Big chunks of raw red onion can overpower; a fine dice spreads that sharp-sweet flavor evenly.
- Don’t skip the rest. Even 10 minutes in the fridge lets the beans soak up the lemon-oregano dressing.
- Season boldly. Beans love salt and acid — taste at the end and add another squeeze of lemon or pinch of salt if it needs it.
Make-Ahead and Storage
This salad is a meal-prep dream. Assemble everything except the feta, cover, and refrigerate for up to 3 days — the flavors get even better overnight. Add the feta just before serving so it stays creamy and fresh. Stir gently before serving and brighten it with an extra squeeze of lemon if needed.
Easy Variations
- Add capers: Two tablespoons of drained capers give the salad an extra briny kick.
- Serve over greens: Pile it onto arugula or chopped romaine for a heartier plate.
- Make it a sandwich: Stuff the salad into warm pita pockets or spoon it over toasted sourdough.
- Swap the beans: Great Northern or navy beans work just as well as cannellini.
- Add crunch: Diced cucumber or celery adds extra freshness and texture.
