Very typical plate of Naples is also spaghetti a vongole (spaghetti with clams), which is also traditionally eaten in the Christmas dinner of the 24th of December.
A classic of the Neapolitan cousine is friarielli, green local fried vegetables which are often served with salsicce (sausages). Many people in Naples consider salsicce e friarielli as a couple in love, so you may find them together on pizzas or inside a sandwich.
Do not forget also that the Campania, the region of Naples, is the native land of the real and fresh mozzarella di bufala (buffalo mozzarella) which is very often served in the caprese, a type of salad done with tomatoes and basil. Please forget the industrial cheese of your supermarket: here in area of Naples the mozzarella is still produced with milk of local buffalos accordingly to old recipes.
