Combine the Italian Herbs, garlic powder, paprika, salt and pepper in a small dish and sprinkle on both sides of the chicken breasts.
Heat a large, oven safe, skillet over medium heat and add the olive oil. Sear the chicken for 3 minutes on each side, then carefully place the skillet in the preheated oven and cook chicken until the internal temperature reaches 165 degrees (about 20 minutes).
Remove skillet from oven and place the thick slices of mozzarella on each chicken breast. Scatter the tomatoes around the chicken in the skillet. Return the skillet to the oven and turn on the broiler for 2 to 3 minutes, or until the cheese is melted. Use a spoon to scoop up the tomatoes and place on top of the cheese and then top with the fresh basil and a drizzle of balsamic vinegar. Enjoy!
