TOD:
Number one all-time favorite without any qualms, hesitations or quibbling: Spaghetti Carbonara (prepared "properly").
Number two favorite: Tortellini a la Bolognese (a chicken- or pork-filled tortellini with meat sauce. YUM!)
Number three favorite: Spaghetti a la Bolognese (spaghetti with meat sauce).
Number four favorite: Spaghetti with pesto sauce.
Of course, parmesan is expected to embellish each of the dishes. And cracked pepper. And red wine.
