Feeding more than 80,000 hungry fans and 20,000 workers at New Jersey's MetLife Stadium is no small job for Delaware North Sportservice, which has been in business almost 100 years but is catering its first Super Bowl.

"It has been in the planning ever since it was announced four years ago," said Bill Lohr, who as general manager of Delaware North Sportservice oversees operations.

The Buffalo, N.Y., company has hired more than 3,000 food workers and 200 chefs to ensure that football's biggest day of the year goes off without a hitch.

MetLife Stadium Executive Chef Eric Borgia estimates that his team will prepare more than 21,500 hot dogs, 75,000 chicken tenders and 12,000 pretzels for the game.

Delaware North is also incorporating local favorites into its offerings, such as its Kitchen Sink Sausage Sandwich and Nonna Fusco's Meatball Hoagies. The company will cook 20,000 meatballs and sausages and 500 gallons of marinara sauce for the sandwiches.

"It was very important for us to have the flavors of New York and New Jersey present at the Super Bowl," Borgia said.

Like the fans and both teams, Delaware North is bracing for cold weather.

"We're prepared to sell 50,000 cups of hot chocolate and coffee," said Lohr. That's about five times as many as sell during a typical NFL game.

The company expects fans to be extra hungry as a result of the NFL's "no tailgating" policy this Super Bowl.

"No tailgating would naturally help a concessionary," Lohr said. "It's up to us to step up our game and make sure we have a wide variety of options for fans to choose from once they get into the stadium."
