Preheat oven broiler.
Heat 2 tsp to a medium skillet over medium high heat. Salt and pepper your pounded out chicken breasts and add them to the pan in batches. Cook for 3-5 minutes per side and place on a baking sheet. Cook remaining 2 chicken breasts and add to the same baking sheet.
While chicken is cooking, slice the tomatoes and mozzarella into 8 slices each.
Once chicken is cooked, place 2 slices of tomato on each chicken breast. Top each tomato slice with a basil leaf and then a slice of mozzarella. Lightly salt and pepper the tops.
Place baking sheet under the broiler for 1-2 minutes until melted.
Place the cheesy chicken on the plate, drizzle with balsamic glaze and sprinkle extra basil over the top.
Serve with rice or quinoa and enjoy!
