For The Filling: Italian Pork Sausage Ground Beef Shredded Mozzarella Yellow Onion
Preheat oven to 350˚F and arrange a rack in the center.
Then make the filling by combining Italian sausage, ground beef, mozzarella and pecorino cheeses, onion, spinach, basil, eggs, garlic, shredded potatoes and spices in a bowl and mix well.
Next, prep the cucuzza squash: Slice off and discard the ends, then peel it.
Then, slice the squash pieces in half lengthwise and deseed them using a small spoon or grapefruit spoon. Cut the squash into smaller pieces, about 2 to 3” long each.
Season the hollowed-out surface of each squash piece with a light sprinkling of salt and pepper. Place tomato sauce on the bottom of a baking dish(es).
