Spray a baking pan lightly with cooking spray. Wrap each chicken strips around each cheese cube and secure with a toothpick. Dip chicken in olive oil and then roll in bread crumbs. Place chicken in the baking pan. Top with bay leaves and sliced onions. Bake for 15 to 20 minutes, or until chicken is fully cooked through, and cheese has melted, and bread crumbs are golden brown. Serve.
