Have you ever added capers to tuna salad? It’s absolutely DELISH! Since trying this combination a few months ago, I’ve been hooked. Unlike the traditional version, this tuna caper salad is incredibly satisfying—packed with crunchy vegetables and made with Greek yogurt instead of mayonnaise for a protein boost.

It’s quickly become my go-to recipe for a quick, delicious meal. Perfect for lunch, dinner, or a snack, you can enjoy it anytime. I love preparing a batch for a speedy lunch at home. Serve it as a salad, wrap it up, or pair it with crackers for a light meal.

Ingredients You’ll Need

Just 9 key ingredients come together to make this healthy tuna salad with capers:

• Tuna: Choose a good-quality skipjack tuna that is pole and line caught (ie no nets, best) in spring water for the best flavour.
• Veggies: Cucumber, tomato, and red onion add crunch and freshness. Mince the onion finely to avoid it overpowering the dish.
• Greek Yogurt: Low-fat Greek yogurt replaces mayo, making the salad creamy and protein-packed.
• Lemon Juice: A squeeze of fresh lemon juice brightens and freshens the flavors.
• Dijon Mustard: Adds a touch of sharpness and a little kick.
• Capers: Briny and tangy, capers elevate the salad with their bold, savory flavor.
• Basil: Finely chopped basil adds a fresh, aromatic finish. You can also substitute parsley or dill for variety.
