Let bread soak in milk for about 15-20 minutes (or until softened) add the meat to the bowl then the flavored bread crumbs, add 1 cup of basic tomato sauce with 1/2 cup of parmesan cheese and the eggs. Mixall the ingredients together.
Next, lay out a large piece of wax/parchment paper and turn out the meat on the paper and flatten into a 14x9 rectangle. Now layer the prosciutto and provolone down the center of the meat. Using the wax paper begin to roll the meat; roll 3 times - gently pressing down on each roll.
Once rolled up seal any gaps and tuck in the edges.
Put in a baking dish and pour remaining tomato sauce on top. Spread out sauce evenly. Place in the oven and bake for 1 hour or until done. Let stand before cutting or cheese will ooze out.
