Prepare pie crust and refrigerate while cooking meat.
Place ground beef, Italian sausage, garlic and onion in skillet till meat is browned. Drain any excess grease. Add enough sauce to pan to make the meat moist, but NOT soupy or saucy.
Add Italian seasoning and basil. Simmer for 10 min. Meanwhile roll out pie crust large enough to fit in a 12" deep dish skillet or pan.
Place a large piece of parchment paper in bottom of pan, this will allow for easier removal, unless using a springform pan. Place dough in pan, I used a cast iron skillet. Make sure dough comes almost all the way up the sides of the pan.
Spoon in just enough sauce (not meat mixture) to barely cover bottom.
Add slices of fresh mozzarella. Spoon in all of meat mixture.
Top with Bruschetta Jack cheese (or your favorite Italian blend). Tears pieces of prosciutto and drop on top of pie as well as Parmesan cheese.
Bake 375° for 50 min. Allow to cool for 15-20 min before removing from pan.
