Finto means fake, so this is a "fake" sauce: It originated with farmers who wanted the body and heartiness of a regular red sauce but couldn't afford the meat. The chunks of onion, carrot, and celery provide the meat-like texture, while the use of red wine gives it added color and depth. Of course, for all you vegetarians, lack of meat may make this more "real" for you than "fake"!
Add the tomatoes and break them down roughly with a wooden spoon. Add the 1 tablespoon parsley and season with salt and pepper to taste. Stir well and cook over low heat for 30 to 40 minutes until the sauce thickens and the flavors blend.
