Cart Driver’s Spaghetti

I wanted to include this recipe, despite it being in one of my previous books, as it is an example of something rather alien to me - virtually none of the ingredients in the dish is fresh! It is said to have been made by the cart drivers transporting goods from the provinces to Rome: hungry on the long journey, they would want to make themselves something that would not go off, that was quite undemanding, and that would still be delicious.
