Prepare your vegetables by dicing the cucumber and chopping the olives and dill. Set aside in separate bowls.

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

Combine the canned tuna, Greek yogurt, diced cucumber, chopped olives, dill, and lemon juice with the mashed avocado.

Mix thoroughly until well-incorporated, ensuring a uniform texture.

Taste and adjust seasoning if necessary. Serve in lettuce wraps, pitas, or atop greens.
