In a medium mixing bowl, combine the drained and flaked tuna with the mashed avocado. Stir together until you achieve a smooth, well-blended mixture.
Next, introduce the Greek yogurt (or mayo), Dijon mustard, and fresh lemon juice into the bowl. Mix thoroughly until all ingredients are fully integrated.
Gently fold in the finely chopped celery, red onion, and fresh dill, ensuring they are evenly distributed throughout the mixture.
Carefully season with salt and freshly cracked pepper to taste. Be sure to taste and adjust the seasoning to enhance the flavors according to your preference.
To assemble your wraps, take a large lettuce leaf and spoon a generous portion of the tuna salad mixture into the center.
For a pop of color and flavor, garnish the filling with halved cherry tomatoes, placing them right on top of the tuna salad.
Carefully fold the sides of the lettuce leaf over the filling to create a wrap. Serve immediately for the freshest taste, or refrigerate for a brief time to enjoy later.
