When I was filming in Naples last year I had some brilliant versions of marinara sauce, on pizza, pasta and with big bowls of seafood. They aren’t afraid of using chilli in southern Italy, and while you can make this dish with tomatoes, fresh or tinned (the local variety San Marzano are some of the best in the world), I quite like the simplicity and punch you get from just using garlic, wine and chilli. The pangrattato (breadcrumb mixture) isn't strictly necessary, but it adds extra crunch and a bit of carb on carb never did anyone any harm.
