$1 OFF Jack in the Box Mini Sirloin Burgers

SAN DIEGO, March 30, 2009 – Bigger isn’t always better … just ask an SUV owner filling up their gas tank. To prove that good things do indeed come in small packages, Jack in the Box® restaurants today introduce Mini Sirloin Burgers – beefy, high-quality hamburgers that are ideal for sharing with friends or as a satisfying meal for one.

Jack’s new Mini Sirloin Burgers feature a trio of all-sirloin patties, which are seasoned while cooking, topped with American cheese, grilled onions and ketchup served on small, bakery-style buns reminiscent of Hawaiian sweet rolls.

“Mini burgers and sandwiches are increasing in popularity throughout the restaurant industry,” said Teka O’Rourke, director of menu marketing and promotions for Jack in the Box Inc. “Our new Mini Sirloin Burgers match the premium quality and taste of similar items offered at casual-dining restaurants and trendy burger bars, but for a quick-serve restaurant price.”

Mini Sirloin Burgers are available now for the suggested price, excluding tax, of $3.89 at all participating Jack in the Box restaurants.
