Put a pizza stone or upside-down baking sheet in the oven; preheat to 500 degrees F.
Make the chicken: Combine the salt, cayenne, white pepper, garlic powder, black pepper, cumin and dried basil in a bowl. Brush the chicken with olive oil, then rub with the spices. Heat a grill pan to medium high; grill the chicken until cooked through, about 7 minutes per side. Grill the sausage, turning, until cooked through, 10 to 12 minutes. Let cool, then dice the chicken and crumble the sausage.
Stretch the pizza dough on a floured surface into a 12-inch round. Put on a cornmeal-dusted pizza peel or upside-down baking sheet; slide the dough onto the hot pizza stone or baking sheet and cook 7 minutes.
Slide the crust back onto the peel. Spread with the pizza sauce, then top with 1/2 cup mozzarella, the chicken, pepperoni and sausage. Sprinkle with the remaining 1/2 cup mozzarella and the parmesan. Return the pizza to the oven and bake until bubbly, about 7 more minutes. Top with the fresh basil.
