Ingredients

Tuna Salad

  • 2 cans tuna 5 ounces each, oil-packed or water-packed
  • 2 tablespoons olive oil extra virgin
  • ¼ cup red onion sliced thin, about ¼ of an onion
  • 4 tablespoons lemon juice or to taste
  • 2 stalks celery finely chopped
  • ¼ cup fresh dill picked from the hard stem and roughly chopped or torn into pieces
  • ¼ cup fresh parsley picked from the hard stem and roughly chopped or torn into pieces
  • kosher salt and black pepper to taste

Optional

  • 2 tablespoons Greek yogurt or to taste
  • 2 teaspoons dijon mustard optional
  • 2 tablespoons capers or chopped cornichons

Instructions

  • Add the onion to a bowl and drizzle the lemon juice over. Let sit for a few minutes to let the flavor absorb.
  • Add the tuna, celery, olive oil, herbs, dijon, salt and pepper, and Greek yogurt if using, to the bowl. Mix thoroughly and taste for seasoning.
  • If using capers or cornichons, sprinkle over the top of the finished tuna salad. Serve.

Notes

General
  • 1 can of tuna can be used for 1 to 2 people, depending on appetites.
  • Approximate calories are based on half of a can of tuna per person and include the option for Greek yogurt, dijon, and capers.
Storage
  • This tuna salad is best stored in the fridge in an airtight container for up to 3 to 5 days.
  • Be sure to move to the fridge within 2 hours.
  • I do not recommend you freeze tuna salad.
