This pasta dish was one of the best things we ate during our trip to Southern Italy. It was prepared for us by Giancarlo Suriano, whose condiment company specializes in preserving regional ingredients, such as Calabrian chilies and Tropea onions. He added chopped walnuts, chilies and oregano to simple toasted breadcrumbs, amping up the flavor and texture of the pantry-friendly dish. To mimic the fruitiness of Calabrian chilies, we opted for Fresnos, which are easier to come by in the U.S. They’re spicier than Calabrian chilies, though, so we seed them to temper the heat. If you prefer a kick, leave the seeds in one or both of them. Red pepper flakes also work well, just add half to the breadcrumb mixture and half with the anchovies, as you would the fresh chilies.
