Serve it as an appetizer with one of my Mediterranean Main Dishes or on its own with Homemade Overnight Focaccia.

Why This Recipe Works

- So easy to make: This is a true mix-and-go salad. No cooking required, and it comes together in under 15 minutes with pantry staples.
- Pairs beautifully: Serve with crusty sourdough or my homemade focaccia. It also works great as part of a large mezze spread with other Mediterranean Salads and Appetizers.
- My version of fagioli e tonno: This recipe is inspired by the classic Italian White Bean and Tuna salad.
Ingredients
This is a great back-pocket recipe with simple ingredients that you probably have right now sitting in your pantry and fridge. Here is what you will need:

- Tuna: Canned in olive oil is ideal, but water-packed works too. Use a good quality tuna if you can find it (sometimes you’ll find it sold in jars rather than cans, and you’ll be able to see whole chunks sitting in oil).
- Canned beans: I like cannellini, white navy beans or white kidney beans for their creamy texture. Chickpeas can be substituted. Or you can use butter beans, like in my Greek Butter Bean Salad.
- Capers: I always have capers in brine on hand and use them in many of my Greek and Mediterranean recipes, like my Mediterranean Salmon Salad, Greek Potato Salad or Sicilian Pesto.
- Dijon Mustard: Adds a subtle sharpness to the dressing, but most importantly it helps emulsify the acid and oil. You end up with a creamy dressing instead of one that splits. I use it in many recipes like my Steak Caesar Salad with Tahini.
- Arugula or Mixed Greens: You don’t need to add the greens, but I like to use them to bulk up the salad a bit and stretch it for a crowd. The greens add a fresh, peppery bite at the end.
- Fresh Herbs: I am using fresh parsley in this recipe, but you can use fresh basil too.

How to Make this Tuna & White Bean Salad Recipe

Step 1. Make the Vinaigrette. In a small bowl, whisk together olive oil, lemon juice, chopped capers, Dijon mustard, grated garlic, salt, and black pepper until emulsified.

Step 2. Assemble the Base. In a large mixing bowl, combine the tuna, white beans, diced red onion, chopped celery, and fresh parsley.

Step 3. Dress the Salad. Pour the vinaigrette over the tuna mixture and gently fold to combine. Try to keep some of the tuna in larger flakes for texture.

Step 4. Add the Greens. Just before serving, gently fold in the peppery arugula or mixed greens. Taste and adjust seasoning if needed. Serve immediately or chill briefly before serving.
Expert Tips
- Don’t overmix the tuna. Folding gently preserves the texture and keeps it from becoming mushy.
- Let it chill if time allows. Let the dressed salad sit for 15-20 minutes in the fridge before adding the greens. The flavors deepen beautifully.
- Make it your own. Swap arugula for baby spinach, add cherry tomatoes, artichoke hearts or sliced olives, or top with shaved Parmesan for extra flavor. Add a splash of red wine vinegar, or maybe some chili flakes. Have fun with it. Check out some of my other Salad Recipes for inspiration.

Recipe FAQs
Yes! You can prepare the tuna, beans, and dressing mixture up to 2 days ahead. Just wait to add the greens until right before serving.
Store any leftover salad in an airtight container in the fridge for up to 3 days. If possible, store the greens separately to prevent wilting.
