Preheat oven to 350 degrees.
Sprinkle salt and pepper on both sides of chicken breasts.
In a large skillet, heat olive oil on medium low heat. Add chicken breasts and cook 2-3 minutes until lightly browned. Flip and cook an additional 2-3 minutes. (Note: The chicken will not be cooked all the way through.)
Place the chicken in a large baking dish that has been sprayed with non-stick spray.
In a small bowl, combine the tomatoes, oregano, basil, garlic, and vinegar. Pour the tomato mixture over the chicken.
Place in the oven and bake for 20 minutes or until chicken is fully cooked.
While the chicken is baking, cook the thin spaghetti.
Serve the Bruschetta Chicken over the pasta and top with Parmesan.
