Ingredients Method

Ingredients
  

  • 2 5-ounce cans solid white albacore tuna packed in water, drained well
  • 1 large English cucumber diced (about 2 cups)
  • 3 celery stalks thinly sliced
  • 1/4 red onion finely chopped
  • 3 tablespoons fresh lemon juice from about 1 lemon
  • 2 tablespoons extra virgin olive oil
  • 1 teaspoon Dijon mustard
  • 2 tablespoons chopped fresh dill
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • Lemon wedges for serving optional

Method
 

  1. Drain the tuna well and transfer to a medium bowl. Use a fork to break it into flakes.
  2. Dice the cucumber into 1/2-inch pieces. Thinly slice the celery stalks. Finely chop the red onion.
  3. In a small bowl, whisk together the lemon juice, olive oil, Dijon mustard, salt, and pepper until well combined.
  4. Add the diced cucumber, sliced celery, and chopped red onion to the bowl with the tuna.
  5. Pour the lemon dressing over the tuna and vegetables. Add the chopped fresh dill.
  6. Gently fold everything together until evenly combined. Be careful not to overmix—you want to maintain some texture.
  7. Let the salad rest at room temperature for 10 minutes to allow the flavors to meld.
  8. Taste and adjust seasoning if needed. Serve immediately with lemon wedges on the side if desired.
