Preheat the oven to 375 degrees F.
In a large saute pan, add the pork and beef with a little olive oil, salt, and pepper, and saute until no longer pink, about 3 to 4 minutes. Set aside to cool.
In a deep, rectangular lasagna pan, add a thin layer of sauce to the bottom, then layer the lasagna strips evenly across the bottom of the pan to cover the entire surface, about 8 sheets of pasta.
Sprinkle 1/4 of the cooked meat mixture over this, then lay out 8 slices of mortadella on top. Sprinkle 1/4 of the cubed mozzarella and 1/4 of the grated cheeses and top with a layer of tomato sauce.
Repeat with another layer of 8 lasagna sheets to cover, then do a layer of prosciutto, mozzarella, another 1/4 of the grated cheese, 1/3 of the chopped herbs, another 1/4 of the cooked meat, and tomato sauce. Finish this layer with 1/2 of the chopped hard-boiled eggs.
Repeat with another layer of lasagna, remaining prosciutto and mortadella, another 1/4 of the grated cheeses, another 1/3 of the chopped herbs, remaining chopped eggs, another 1/4 of the mozzarella, another 1/4 of the cooked meat, and sauce.
Repeat with the last layer of lasagna, remaining cooked meat, remaining grated cheeses, remaining mozzarella, and a thin layer of tomato sauce. Sprinkle the top layer with the remaining chopped parsley and basil and fresh cracked black pepper.
Cover with aluminum foil and bake for about 1/2 hour, until cheeses melt and ingredients have melded. Try not to let the aluminum foil touch the top layer or the cheese will stick when you uncover.
Uncover and let cool and set for about 1/2 hour before cutting so lasagna can absorb the liquid released by the cheeses.
Note : There is no salt in this recipe because the cheeses and meats should be salty enough to balance the flavors.
