If you find yourself with leftover Tuscan cream sauce ingredients like heavy cream, sun-dried tomatoes, spinach, or Parmesan, this makes an easy and delicious next-day or weekend sandwich. Simply pick up a loaf of rustic bread and an extra chicken breast or two, make a quick batch of the sauce, and spoon it generously over the chicken. It is simple, cozy, and feels just as special the second time around.
