Preheat your oven to 400°F (200°C). Grease a baking dish large enough to accommodate the chicken breasts.
Place chicken breasts in the baking dish and drizzle one tablespoon of olive oil. Then sprinkle salt to taste.
In a bowl, combine the diced tomatoes, minced garlic, chopped basil, and the other tablespoon of olive oil. Toss until well coated.
Spoon the tomato mixture over the chicken breasts, making sure to distribute it evenly.
Bake in the preheated oven for about 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
Remove the baking dish from the oven and sprinkle the shredded or diced mozzarella cheese over the chicken and tomato mixture.
Return the dish to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let the chicken rest for a few minutes.
Drizzle balsamic glaze over the top of the chicken breasts.
Serve the Bruschetta Chicken Bake hot, garnished with additional fresh basil leaves if desired.
