Begin by preheating your oven to 375°F (190°C). Pat the chicken breasts dry with paper towels, ensuring they’re not too wet for the skillet. This step allows for perfect browning.

In a bowl, season the chicken breasts with kosher salt, freshly ground black pepper, and garlic powder. Give them a good rub, ensuring the seasoning gets into every nook and cranny. This part is crucial; it's where flavor begins.

In a large skillet, heat a generous drizzle of extra-virgin olive oil over medium-high heat. Once hot, add the seasoned chicken breasts. Searing creates a delicious crust, locking in moisture. Cook each side for about 4-5 minutes or until golden brown.

Once the chicken is seared, spread a dollop of basil pesto over each breast. Then, place the slices of fresh mozzarella on top. Don’t be shy with it; more is more! Transfer the skillet to your preheated oven. Bake for 15 to 20 minutes or until the chicken is cooked through (165°F or 74°C).

While the chicken bakes, slice your ripe tomato and prepare the basil. As soon as the chicken is ready, remove it from the oven. Top each piece with tomato slices, fresh basil leaves, and a drizzle of balsamic glaze. For an extra kick, sprinkle crushed red pepper flakes.

Serve this delightful dish over a bed of mixed greens or alongside grilled vegetables. Each bite is sure to transport you to a sunny Italian terrace, with laughter and good food all around.
