Crunchy Herbed Tuna Salad

The cucumbers and herbs make this tuna salad light and summery, and the zippy oil-and-vinegar dressing keeps it that way. It’s delicious in a sandwich or scooped onto a bed of greens.

Kitchen Gear

Cutting board
Sharp knife (adult needed)
Measuring spoons
Can opener
Strainer or colander
Small bowl
Spoon, for mixing
Medium-sized bowl


1⁄4 small red onion, peeled and diced
2 tablespoons red wine vinegar
2 tablespoons olive oil
1 tablespoon chopped fresh dill (or 2 teaspoons dried)
1 teaspoon dijon mustard
1⁄4 teaspoon kosher salt
2 (5-ounce) cans tuna, any kind, drained in a strainer or colander
1⁄2 English cucumber (the plastic-wrapped kind, diced, or 1 regular cucumber, peeled, seeded, and diced)
1 celery rib, diced


Wash your hands with soap and water, then gather all your equipment and ingredients and put them on a counter.

  1. Put the onion and vinegar in the small bowl, stir well, and set aside for 15 minutes. (This will help the onion to mellow so it’s not so sharp-tasting.)
  2. Put the oil, dill, mustard, and salt in the medium-sized bowl and mix well.
  3. Add the tuna, cucumber, and celery, and mix well.
  4. Add the onion and vinegar and mix again.
  5. Serve right away, or cover and refrigerate up to overnight.


Try the following to make it:
Beany: Add 1 can white beans, drained and rinsed.
Herbier: Pull the leaves out from inside your bunch of celery, and chop 2 tablespoons. Add them in addition to (or instead of ) the dill.
Sweet: Add 1⁄2 cup seedless grapes, cut in half.
