Heat flat top griddle to medium. Add all meats (sausage, salami, mortadella, ham). Cook about 1 minute, then add garlic, onion, tomatoes, and bell pepper. Saute everything together until vegetables soften.
Add orzo, green olives, and Italian seasoning. Toss everything until well combined. Let sit briefly to toast the orzo, then work together for 2–3 minutes.
Add Parmesan, white wine, olive oil, and mozzarella. Toss to combine and let the liquids reduce. Fold in the mozzarella until melted and integrated. Transfer to a serving dish.
Garnish with fresh basil, extra Parmesan, a drizzle of balsamic glaze, and a drizzle of olive oil. Serve immediately.
