Prepare a deep container for the filling. Cut the boiled eggs into small cubes, chop the parsley. Grate the cucumbers and hard cheese. Mix everything in one container, add cream cheese and garlic sauce.
Spread the filling over the entire lavash, grease the edges of the sheet with cream cheese if desired, then roll it up. Wrap it in film and leave it in the refrigerator for a while so that it soaks better and is easier to cut.
