Cavatappi is hollow, corkscrew shaped pasta. I know I have said that I prefer strands with red spaghetti sauce but John likes shapes so we compromised. It turned out to be really delicious! I took a cup of leftover Rao’s tomato and basil sauce and added V-8, tomato paste, oregano, chile flakes, and oregano. Doing this expanded the amount of sauce I had. The meatballs were simply Rosina’s frozen home style meatballs I added them, still frozen, to the sauce as I was cooking it.
