Ingredients

For the Zesty Dijon Mustard Dressing:

  • 2 1/2 teaspoons Dijon mustard
  • Zest of 1 lime
  • Juice of 1 1/2 limes
  • 1/3 cup extra virgin olive oil
  • 1/2 teaspoon sumac
  • Pinch of kosher salt and black pepper
  • 1/2 teaspoon crushed red pepper flakes optional

For the Tuna Salad:

  • 3 cans 5 ounces each quality tuna (such as wild-caught Albacore or Yellowfin), drained
  • 2 1/2 celery stalks chopped
  • 1/2 English cucumber chopped
  • 4-5 radishes chopped
  • 3 green onions chopped (white and green parts)
  • 1/2 medium red onion finely chopped
  • 1/2 cup pitted Kalamata olives halved
  • 1 bunch parsley stems removed, chopped (about 1 cup)
  • 10-15 fresh mint leaves stems removed and finely chopped (about 1/2 cup)

Instructions

Make the Dressing:

  • In a small bowl, whisk together Dijon mustard, lime zest, and lime juice.
  • Slowly drizzle in the olive oil while whisking to emulsify.
  • Add sumac, salt, pepper, and crushed red pepper flakes (if using). Whisk until well combined. Set aside.

Prepare the Tuna Salad:

  • In a large salad bowl, combine drained tuna, celery, cucumber, radishes, green onions, red onion, olives, parsley, and mint.
  • Gently mix with a wooden spoon until evenly combined.

Assemble the Salad:

  • Pour the dressing over the salad and gently toss until well coated.
  • Cover and refrigerate for at least 30 minutes to allow the flavors to meld.

Serve:

  • Toss the salad once more before serving.
  • Serve in warm pita sandwiches, lettuce wraps, or as a topping over roasted tomatoes.

Notes

Best Tuna Options: Use wild-caught Albacore or Yellowfin tuna for optimal flavor and quality. For a lower-fat option, choose tuna packed in water instead of oil.

The dressing can be made up to 2 days in advance and stored in a Mason jar in the refrigerator.
