This is my Big Fat Ziti al Forno for celebrations, parties, etc.... Its big, fat, and  filled with lots of wholesome bites of comforting goodness! Its very Neapolitan in that you use left over meatballs from a previous made ragu and a little this (salami) a little that (provolone)....... Its kind of a combo of my every day ziti al forno, gato', and Casatielle, all baked into one magnificent dish, Magnifico!
Ingredients

1/2 cup grated paremsan cheese (use the largest grate)
4-6 slices provolone diced
8 ounces salami cut up
1 teaspoon salt
2 eggs 
3 cups left over Ragu sauce along with enough meatballs to make about 1 layer covering the pan (Cut the meatballs in half if they are large about 1 inch pieces)

Mixture before adding pasta.

a little pasta water
bread crumbs and olive oil for top
Directions
Boil pasta in very salty water, reserve about 1 cup of water and drain the pasta out
Coat a large lasagna pan in olive oil and make a light dusting of bread crumbs on the bottom
Mix all the ingredients except the pasta straight in to a bowl .
Add the pasta and enough pasta water to form a wet mixture and stir to combine.
Dump in the pan.
Make another light dusting of bread crumbs and drizzle olive oil all over top.
Cover in foil and bake 25 minutes.
Remove foil and bake until golden brown on top, another 15 minutes or so.
