This no mayo tuna salad is a perfect light lunch idea. It is made with onions, herbs and a lemon based dressing. It is healthy and low-calorie yet so tasty and filling.




  • 1 5-ounce can tuna (145g), drained
  • 1 small red onion, chopped finely
  • ¼ cup chopped fresh dill
  • ½ cup chopped arugula


  • Juice of half lemon
  • 1 tablespoon olive oil
  • ½ teaspoon salt
  • ½ teaspoon black pepper


  1. In a large bowl, flake the tuna fish meat using a fork. 
  2. Add in chopped onion, fresh dill and arugula.
  3. Make the dressing by simply whisking lemon juice, olive oil, salt and pepper.
  4. Pour the dressing over the salad and give it a good stir.
  5. Serve it on its own or make a sandwich.


  1. If you are looking for a diet tuna salad recipe, you might prefer tuna in water. It will add fewer calories, but unfortunately also less flavor. This is easily fixable though by adding spices or herbs (which contain very few calories and lots of flavors).
  2. When using tuna in oil, make sure to drain it well before flaking it. This will make your tuna salad less oily and help enhance the accompanying flavors.
  3. Do not cook or heat canned tuna. It is already cooked and you can have it at room temperature. This is what makes canned tuna a perfect ingredient for salads and sandwiches. 
  4. You can store the leftovers in an airtight container  and keep it in the refrigerator for 1-2 days. And we don't recommend freezing this salad.
