Ingredients
  

For the Salad:

  • 2 lbs baby red and/or Dutch gold potatoes halved
  • 7 –10 oz canned tuna in water or oil drained
  • ¼ red onion thinly sliced

For the Lemon Dressing:

  • 3 Tbsp olive oil
  • 3 Tbsp lemon juice freshly squeezed
  • 1 Tbsp lemon zest
  • 3 Tbsp capers in brine
  • Tbsp whole grain mustard or Dijon
  • 2 garlic cloves minced
  • ½ tsp dried dill
  • ½ tsp dried basil
  • ¼ tsp salt more to taste
  • ¼ tsp ground black pepper
  • 3 Tbsp fresh cilantro chopped

Instructions
 

Boil Potatoes:

  • In a large pot, bring water to a boil. Add a heavy pinch of salt. Add halved baby potatoes and cook for 10–14 minutes, until fork-tender but not mushy.

Drain and Cool:

  • Drain the potatoes and let them cool slightly. Rinse briefly with cold water to stop cooking. Set aside.

Prepare Tuna:

  • Drain tuna thoroughly using a mesh strainer. Lightly press to remove excess liquid. Flake gently with a fork.

Make the Dressing:

  • In a mixing bowl, whisk together olive oil, lemon juice, lemon zest, capers, mustard, garlic, dill, basil, salt, pepper, and chopped cilantro until well combined.

Assemble Salad:

  • In a large bowl, combine cooled potatoes, flaked tuna, sliced red onions, and the lemon dressing. Toss gently to coat without breaking up the potatoes.

Chill & Serve:

  • Refrigerate for at least 30 minutes before serving. Stir gently before plating. Enjoy cold or at room temperature.

✅ Make-Ahead Tip:

  • You can cook the potatoes and prepare the dressing a day ahead. Store separately and mix before serving.

✅ Storage:

  • Keep leftovers in an airtight container in the refrigerator for up to 4 days. Do not freeze.
