Ingredients

Scale

Tuna Salad

  • 5 ounces wild-caught tuna (canned)
  • 1/4 cup red or yellow onion, chopped
  • 2 tablespoons clean mayonnaise, plus more to taste
  • 1/2 teaspoon kosher or sea salt
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon paprika
  • 1 tablespoon freshly squeezed lemon juice (from 1/2 a lemon)

Assembly

  • 2 cucumbers, partially peeled lengthwise to create stripes, cut into 12 horizontal slices each

Instructions

  1. Prepare Tuna Salad: In a medium bowl, combine the wild-caught tuna, mayonnaise, chopped onions, kosher or sea salt, black pepper, paprika, and freshly squeezed lemon juice. Mix thoroughly until all ingredients are well incorporated into a creamy tuna salad.
  2. Assemble Sandwiches: Arrange half of the cucumber slices on a clean serving surface. Spoon a dollop of the prepared tuna salad onto each cucumber slice, spreading slightly to cover the surface.
  3. Complete Sandwich: Top each tuna-covered cucumber slice with another cucumber slice to form a sandwich. For easier handling, optionally secure each sandwich with a toothpick.
  4. Serve and Enjoy: Serve the cucumber tuna sandwiches immediately. Enjoy this fresh, light, and gluten-free alternative to traditional tuna sandwiches, perfect as a quick snack or light meal.

Notes

  • Use wild-caught tuna for the best flavor and quality.
  • Partially peeling the cucumbers lengthwise creates attractive stripes and a better texture contrast.
  • Feel free to adjust the amount of mayonnaise to achieve your preferred creaminess.
  • To keep sandwiches fresh, prepare just before serving as the cucumber slices may release moisture over time.
  • These sandwiches are naturally gluten-free and low in carbohydrates, making them suitable for gluten-free and low-carb diets.
