Preheat the oven to 400 degrees F. Grease 1 large baking sheet and 1 baking pan with olive oil.
Lay the tomatoes down on the baking sheet in one layer. Drizzle lightly with olive oil and sprinkle with Italian seasoning, salt, pepper and Parmesan.
Place the chicken cutlets in the baking pan and season well with salt and pepper.
Bake both about 15 minutes until the chicken is cooked through. Remove them both and heat the broiler.
Cover the chicken with the mozzarella and broil until melted with some brown spots - 2 to 3 minutes. Keep a close eye on them so they don't burn.
To serve top with the tomatoes and basil.
