Meatlovers! Cook proteins before making sauce (use the same large non-stick pan over medium-high heat with 1 tsp. olive oil, no need to wipe clean) and add to baked ziti as desired. If using diced chicken, pat dry and season with a pinch of salt and pepper. Stir occasionally until chicken reaches a minimum internal temperature, 5-7 minutes. If using shrimp, pat dry and season with a pinch of salt and pepper. Cook until opaque and shrimp reach minimum internal temperature, 2-3 minutes per side. If using Italian sausage, remove from casing, if necessary. Break up meat until no pink remains and sausage reaches minimum internal temperature, 4-6 minutes. If using Beyond sausage, break up until warmed through, 6-8 minutes. Vegetarian sausage will not brown.
