Scoop out some of the avocado from the pitted area to widen the "bowl" area. Place the scooped avocado into a medium-size mixing bowl. Mash it with a fork.
Add the chicken, mozzarella, tomato, and basil. Season with salt and pepper. Stir it all together until everything is well mixed.
Scoop the mixture into the avocado bowls. Drizzle with balsamic vinegar or balsamic glaze
