Pizza Hut is well-known in the world of fast-food pizza, but that doesn't mean it can't change, and its next innovation will have you placing an order now.

When it comes to getting creative with crust, no one out-pizzas the Hut. The mega chain recently revised the recipe for one of its longtime pizza styles.

With heaps of nostalgia but little promotion by their parent chain, Pizza Hut Classics take their fervent fans on a time trip back to a simpler, warmer era.
