English cucumbers are ideal for these bright-tasting, bread-free sandwiches because they have fewer seeds than other varieties. To send this in a school lunch, pack the tuna and cucumber slices separately and let the kids assemble the sandwiches themselves.


  • 3 Tablespoon mayonnaise or vegan mayonnaise
  • Grated zest of 2 lemons
  • 1 1/2 Teaspoon fresh lemon juice
  • 1/2 Teaspoon salt
  • 1/4 Teaspoon freshly ground black pepper
  • 2 Tablespoon chopped bread-and-butter pickles
  • 2 5-ounce cans tuna in water, drained
  • 1 to 2 English cucumbers, peeled and sliced ¼ inch thick


Step 1:

In a small bowl, add the mayonnaise, lemon zest, lemon juice, salt, pepper, and pickles. Stir to combine.

Step 2:

Add the tuna, and combine with the lemon dressing. Taste, and adjust the seasonings, if needed.

Step 3:

Assemble the cucumber sandwiches: Spread 1 tablespoon of tuna salad in the middle of 1 cucumber slice and top with a second slice. Repeat with the remaining cucumber slices until all of the tuna has been used. Serve.
