What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 2 large English cucumbers
  • 2 cans tuna in water drained
  • 3 tablespoons mayonnaise
  • 1 tablespoon lemon juice
  • 1 teaspoon dried dill
  • 20 pieces small black olive slices for eyes

Step by step instructions

Step 1: Prepare the Cucumbers

Cut cucumbers into half inch thick rounds. Use a small fish shaped cookie cutter to press through each round, creating fish shaped cucumber pieces. Pat each piece dry with a paper towel to remove excess moisture.

Step 2: Make the Tuna Filling

In a medium bowl, combine drained tuna, mayonnaise, lemon juice, and dried dill. Stir together until the mixture is creamy and well combined. Season with a pinch of salt if desired.

Step 3: Top the Fish Shapes

Place a small teaspoon of tuna mixture onto the center of each fish shaped cucumber piece. Use the back of a spoon to spread it gently without going over the edges.

Step 4: Add Eyes and Serve

Place one small black olive slice on each tuna topped cucumber piece to create a fish eye effect. Arrange all the fish bites on a blue platter decorated to look like the ocean and serve chilled.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • tuna in water → canned salmon for a different flavor profile
  • mayonnaise → Greek yogurt for a lighter and higher protein version

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Not patting the cucumber dry which makes the tuna topping slide off the surface
  • Overfilling each cucumber piece with too much tuna which makes it difficult to eat in one bite
