Rachael's Polpettone with Mortadella and Greens

Preheat oven to 375˚F. Line a quarter-sheet tray or 9x13-inch rimmed baking sheet pan with 2 layers of parchment paper.

In a small bowl, soak bread with half-and-half/milk, and let stand 15 minutes.  

Place meats in bowl. Season with salt, pepper, red pepper, nutmeg, herbs, lemon zest and EVOO. Combine meats and make a well, then add bread, eggs and parm. Mix with meat, then turn meat onto parchment in pan and press into large rectangle to edges.  

Turn pan with long side facing you. Cover the meat with mortadella leaving 1/2 inch space on far long side clear to seal the loaf later when you roll it. Cover the mortadella with spinach, provolone or mozzarella and eggs. Use the parchment to help you wrap and roll the loaf tightly away from you. Push in ends to set the loaf, leaving the spiral exposed, and pull away the paper you used to roll the loaf carefully and press to set on the fresh sheet of parchment underneath. Drizzle the loaf with EVOO.    

Roast the large meatloaf to 160˚F on instant-read thermometer, about 50-55 minutes. Rest 15 minutes and slice.

Alternatively, to make 4 large meatballs/loaves, score the rectangle into 4 rectangles. Leaving a ½-inch border around, top each evenly with mortadella, spinach, egg and cheese. Fold the rectangles to seal the stuffing, forming oval-shaped meatballs. Roast 40 minutes or until instant-read thermometer reads 160˚F. Let rest, slice and/or serve 1 per 2 portions.  

While meatloaf or large meatballs cook, heat a pot over medium heat and melt butter. Add granulated garlic, onion, pepper, and tomato paste, and whisk 1 minute. Add vermouth or wine, stock and passata, then simmer at low bubble until ready to serve.
