Creating Skillet Bruschetta Chicken is straightforward if you follow these simple steps:

1. Prepare Chicken: Flatten each chicken breast slightly for even cooking. Season with salt and black pepper on both sides.
2. Heat Oil: In a large skillet, heat olive oil over medium-high heat.
3. Cook Chicken: Add the chicken to the skillet and cook for about 6-7 minutes on each side, or until cooked through and golden brown. The internal temperature should reach 165°F (75°C).
4. Combine Topping: While the chicken cooks, combine the diced tomatoes, chopped basil, minced garlic, balsamic vinegar, and a pinch of salt in a medium bowl. Mix well.
5. Add Topping: Once the chicken is done, lower the heat to medium. Spoon the bruschetta mixture evenly over the chicken in the skillet.
6. Melt Cheese: If using, sprinkle shredded mozzarella on top of the bruschetta. Cover with a lid and allow the cheese to melt for 2-3 minutes.
7. Garnish: Remove from heat and garnish with additional fresh basil leaves for a pop of color.
8. Serve: Transfer the chicken, with the bruschetta topping, to a serving platter.

Following these instructions will lead to a delicious and visually stunning dish that will impress anyone who sits at your table.
