Carefully slice each avocado in half, lengthwise, and gently remove the pit. Take care to keep the halves intact.
Using a small spoon, delicately scoop out a narrow layer of the avocado flesh from the center of each half to create ample room for the filling. Save the scooped-out avocado for later use.
In a mixing bowl, combine the halved cherry tomatoes, mozzarella balls, and finely chopped basil leaves.
Drizzle the mixture with extra virgin olive oil and balsamic glaze, then season with sea salt and freshly cracked pepper. Gently toss the ingredients together until well-coordinated.
Carefully spoon the tomato and mozzarella mixture into each avocado half, pressing down slightly to ensure each half is generously packed.
For an added layer of creaminess, top the filling with the reserved avocado flesh, diced or sliced into small pieces.
Drizzle a small amount of additional balsamic glaze over the assembled boats for an artistic touch, if desired.
Notes
Arrange the filled avocado halves on a rustic wooden serving board or a brightly colored plate for presentation.
