Carefully slice the avocados in half lengthwise. Gently twist the halves to separate them and remove the pit using a spoon or knife.
With a spoon, carefully scoop out a small amount of avocado flesh from each half, creating space for the filling. Place the scooped avocado flesh in a separate mixing bowl.
In a medium mixing bowl, combine the halved cherry tomatoes, halved mozzarella balls, and finely chopped basil leaves.
Drizzle the olive oil and balsamic glaze over the mixture in the bowl. Season generously with salt and freshly ground black pepper to enhance the flavors.
Gently fold the reserved avocado flesh into the Caprese mixture, being careful not to mash the ingredients. Stir until the mixture is just combined.
Use a spoon to generously fill each avocado half with the Caprese mixture, pressing it down slightly to ensure they are well packed.
For an extra touch of flavor and presentation, drizzle any remaining balsamic glaze over the top of the stuffed avocados before serving.
Notes
Arrange the stuffed avocados on a decorative platter. For an appealing presentation, sprinkle additional chopped basil around the plate and drizzle a little olive oil on top for a fresh touch.
