Being by making the bruschetta. Place the chopped garlic, parsley, basil, tomatoes, salt, pepper, and olive oil into a bowl. Mix to combine and set aside at room temperature.
Next, prepare the chicken. Slice each chicken breast in half across the middle so that you have to thin chicken breasts. This will help the chicken breast to cook faster and more evenly.
Season each side of the chicken breast with salt and pepper and set aside.
Preheat a large frying pan over medium-high heat. Add some olive oil to the pan, followed by the chicken breast. Cook the chicken for 3-4 minutes per side or until golden brown, then flip, and continue to cook for another 3 minutes until fully cooked.
Once the chicken is cooked, reduce the heat to low and top each piece of chicken with mozzarella cheese.
You will notice that there is some juice in the bottom of the bowl of bruschetta. Add the juice to the pan with the chicken, then cover with a lid and cook until the cheese has melted and the sauce has thickened.
Transfer the chicken to a plate and top with the bruschetta topping and extra basil for garnish. Serve immediately and enjoy!
