(January 2013) (Learn how and when to remove this template message) </Td> </Tr> <P> Although best known for its hamburgers, Jack in the Box's most popular product is its taco, which it has sold since the first restaurant in the 1950s . As of 2017, the company sells 554 million a year manufactured in three factories in Texas and Kansas to "a legion of fans who swear by the greasy vessels even as they sometimes struggle to understand their appeal", The Wall Street Journal reported . The newspaper quoted one fan who compared it to "' a wet envelope of cat food"' and observed that "there are two kinds of people: those who think they're disgusting and those who agree they're disgusting but are powerless to resist them". A Los Angeles restaurateur praised it, however, as "the most underrated taco of all time"; celebrity fans include Tom Hanks, Chelsea Handler, Selena Gomez, and Chrissy Teigen . What makes the taco unusual is that it is created with the meat and hard taco shell in the Texas and Kansas facilities, then frozen for transport and storage . At the restaurant, it is then deep fried, then prepared with lettuce, cheese and mild taco sauce before serving . </P> <P> Besides tacos, other Americanized foods from ethnic cuisines that Jack in the Box offers include egg rolls, breakfast burritos, and poppers . New items come in on a rotation every three to four months, including the Philly cheesesteak and the deli style pannidos (deli trio, ham & turkey, zesty turkey) which were replaced by Jack's ciabatta burger and included the original ciabatta burger and the bacon' n' cheese ciabatta . Jack in the Box also carries seasonal items such as pumpkin pie shakes, Oreo mint shakes, and eggnog shakes during the Thanksgiving and Christmas holidays . In some locations, local delicacies are a regular part of the menu . Locations in Hawaii, for example, include the Paniolo Breakfast (Portuguese sausage, eggs, and rice platter) and teriyaki chicken and rice bowl . In the Southern United States, the company offers biscuits and sweet tea . In Imperial County, California, some locations sell date shakes, reflecting the crop's ubiquity in the region's farms . In the spring of 2007, Jack in the Box also introduced its sirloin burger and followed this up recently with the sirloin steak melt . Its more recent foray into the deli market was the less - popular Ultimate Club Sandwich which was initially removed in Arizona due to poor sales and has since been phased out at all locations . </P>
