Thoroughly rinse your cucumber under cold water and dry it completely with a clean kitchen towel. Using a sharp knife, slice the cucumber in half lengthwise, then cut each half in half again to create 4 long boat-shaped pieces.

Take a spoon and carefully scoop out all the seeds and some flesh from each cucumber piece, creating a hollow channel that will hold your tuna mixture. This gives you perfect little cucumber vessels ready for filling.

In a medium mixing bowl, flake the well-drained tuna with a fork. Add the Greek yogurt, mayonnaise, finely diced red onion, fresh dill, and garlic powder. Season generously with salt and pepper, then mix everything together until you have a smooth, creamy salad. Taste and adjust seasoning as needed.

Generously spoon the tuna mixture into each hollowed cucumber boat, mounding it slightly. Serve right away while the cucumbers are still crisp and refreshing.
