In a medium bowl, combine the diced tomatoes, minced garlic, chopped basil, and olive oil. Season with salt and pepper and set aside for 10 minutes to marinate.
Lay the flour tortillas flat on a clean surface.
Spread 2 tablespoons of basil pesto evenly across the center of each tortilla, leaving a 1-inch border.
Divide the shredded chicken and mozzarella pearls evenly among the tortillas, placing them over the pesto.
Spoon the marinated tomato bruschetta mixture over the chicken and cheese.
Drizzle approximately 1 teaspoon of balsamic glaze over the filling of each wrap.
Fold the left and right sides of the tortilla toward the center, then roll tightly from the bottom to form a wrap.
Optional: Heat a dry skillet over medium heat and toast the wraps for 2 minutes per side until the tortilla is golden brown and the cheese is slightly melted.
