"In 1985 Pizza Hut introduced the Priazzo,[5] a two-crusted Italian pie that resembled a deep-dish pizza. Varieties included Priazzo Milano, a blend of Italian sausage, pepperoni, beef, pork fillings, a hint of bacon, mozzarella and cheddar cheese; Priazzo Florentine, a light blend of five cheeses with ham and a touch of spinach, and Priazzo Roma, stuffed with pepperoni, mushrooms, Italian sausage, pork filling, onions, mozzarella and cheddar cheese. The double-crusted pie was topped with a layer of tomato sauce and melted cheese. The Priazzo was introduced by a $15 million advertising campaign, but proved too labor-intensive and was removed from the menu several years later."
