How to make Green bean and tuna salad with basil dressing

  1. Combine the shallot, vinegar, and 1 tsp salt in a blender jar. Allow to sit for 5–10 minutes to lightly pickle.

  2. Meanwhile, cook the green beans in a large pot of boiling salted water for about 4 minutes, until crisp-tender. Drain the beans and immediately run them under very cold water until cool to the touch.

  3. Add the basil, oil, lemon juice, and pepper to the shallot mixture in the blender, then blend until mostly smooth.

  4. Pour the dressing into a large bowl. Add the green beans, lettuce, white beans, parsley, and capers, then toss with your hands to coat.

  5. Gently fold in the tuna to combine.

  6. Transfer the salad to a serving platter.
