In a small bowl, whisk together 0.5 cup olive oil, minced garlic, oregano, salt, and pepper.
Place chicken breasts in a baking dish and pour the olive oil mixture over them, ensuring they are well coated. Bake for 20-25 minutes, or until cooked through and no longer pink in the center.
While the chicken is baking, prepare the bruschetta topping. In a medium bowl, combine diced cherry tomatoes, finely chopped red onion, chopped fresh basil, balsamic glaze, and 1 tablespoon of olive oil. Stir to combine.
Once the chicken is cooked, remove it from the oven. Spoon the bruschetta topping generously over each chicken breast.
Serve immediately.
Notes
This dish is great served with a side of pasta or a fresh green salad.
