With the sliders, Walsh said people "don't have to worry about your mushrooms spilling over on my cheese side."
The sliders aren't the first time Pizza Hut looked overseas for inspiration; the Dinner Box was first introduced in Australia before it came to the United States.
Pizza Hut declined to say whether the sliders have higher profit margins than a regular pie. In terms of how filling they are, Pizza Hut says each slider is roughly the equivalent of a slice, meaning a person might eat two or three. A pepperoni slider has about 260 calories, compared with 250 calories for a slice of a medium pie and 370 calories for a slice from a large pie.
The chain promised earlier that it would give away samples of a mysterious new product if the word "hut" was uttered during the Super Bowl, meaning the giveaway was virtually guaranteed. The chain says customers can get their free sliders between 4 pm and 7 pm Tuesday.
Pizza Hut in the U.S. has had a bumpy past few years, with customers pulling back on spending in recent years. To help grow its business and accommodate changing eating habits, the chain in 2009 introduced a smaller store format that focuses only on delivery and carry-out orders, with no tables for dine-in customers. About 40 percent of its 6,400 locations are now only carry out or delivery.
Pizza Hut is a unit of Yum Brands Inc., which is based in Louisville, Ky. and also owns Taco Bell and KFC.
