Spray a 9x13-inch baking pan with nonstick cooking spray.
Combine bread crumbs and Parmesan cheese in a small mixing bowl.
Place flour and eggs in their own separate bowls.
Dip the chicken breast in the flour, then in the eggs, and then in the bread crumb/cheese mixture.
Place chicken breast in prepared baking pan and then repeat with the remaining chicken breasts. Pour melted butter on top of the chicken.
Bake for 30 minutes or until the inside is no longer pink and reaches 165 degrees F.
While the chicken bakes, mix tomatoes, garlic, oil, cheese, basil, balsamic vinegar, salt and pepper. Let it sit for about 15 minutes so that the flavors can meld together.
When chicken is finished cooking, spoon some of the fresh tomato mixture on each chicken breast and serve.
