Prep your fresh ingredients by washing and drying your cucumber. Dice half of it into small cubes. Chop olives and dill.

Mash the avocado in a mixing bowl until smooth and creamy.

Combine canned tuna, Greek yogurt, cucumber, olives, dill, lemon juice, garlic powder, salt, and pepper in the bowl.

Taste the mixture and adjust the seasoning to your liking.

Serve in lettuce wraps, on toast, or over a bed of greens.
