Spread washed and dried spinach leaves on large platter.
Generously salt and pepper both sides of chicken cutlets. Heat 2 Tablespoons of Olive Oil over medium high heat. Brown chicken about 2 minutes each side.
Lay chicken immediately onto spinach leaves. The warm chicken will wilt the spinach just a bit and marry their flavors.
Drizzle balsamic glaze over chicken.
If needed, add remaining oil to pan and add tomatoes and garlic. Cook just until warmed through over medium low heat.
Layer tomatoes and garlic over chicken and spinach. Pour any remaining liquid from pan over all.
Layer mozzarella balls and then top with basil.
