Preheat your oven to 375.
Cover just the bottom of a nonstick skillet with olive oil and heat it on med-high until hot, being careful not to burn.
Season your chicken and once the oil is hot, place it carefully into the pan.
Cook chicken turning once until the outside is browned and the chicken is cooked through (cook time will vary based on side and thickness of your chicken).
Heat your sauce.
Once your chicken is done assemble the Chicken Italiano stacks by placing a slice of the mozzarella on each piece of chicken followed by a slice of the pepper, Then place it on the oven for 3-5 minutes...Just allow the cheese to begin to melt. Then simply spoon sauce on your plate, place a stack on top, add a little more sauce over-top and for garnish add chopped parsley & shaved Parmesan if you like.
