Combine the Kikkoman Preservative-Free Orange Sauce and the Kikkoman Sriracha Hot Chili Sauce.
Top each 16-inch pizza crust with ½ cup Kikkoman Preservative-Free Orange Sauce. Place 8 ounces of grated mozzarella cheese on each pizza and distribute evenly. Top each pizza with 14.5 ounces of diced fajita chicken, ¼ cup sliced green onions, and 6-8 red bell pepper rings.
Bake in a preheated 375˚F oven for about 8-10 minutes, or until the cheese had melted and begins to brown slightly. Remove from oven and let rest for a few minutes before slicing. Slice each pizza into 8 equal slices. Hold warm at or above 140˚F.
Sprinkle 2 tablespoons of chopped cilantro over each pizza just before service.
