Preheat the grill pan or skillet over medium heat.
Slice ciabatta rolls in half and lightly brush the insides with olive oil.
Place the ciabatta rolls, cut side down, on the grill pan and toast them for about 2-3 minutes, or until golden brown.
In a small bowl, combine the sliced avocado with a pinch of salt and black pepper.
On the bottom half of each toasted ciabatta roll, spread 1 tablespoon of pesto.
Top the pesto with slices of the burrata cheese, followed by tomato slices, avocado, and fresh basil leaves.
Drizzle a bit of balsamic glaze on top of the toppings before placing the other half of the ciabatta roll on top.
Press down gently and serve immediately, or you can cut them in half for easier handling.
Optional: Add extra toppings like arugula or roasted red peppers for added flavor.
Optional: For a spicier kick, consider adding red pepper flakes or your favorite hot sauce.
