During a "Sunday Morning" visit to Philadelphia, correspondent Susan Spencer shares the love for three traditional food favorites in the City of Brotherly Love.The sacred Philadelphia cheesesteakFor more than a few Philadelphians, cheesesteak is a sacred cow. "I hold it close to my heart," said Frankie Olivieri, the third-generation owner of Philly's legendary Pat's King of Steaks. "I tell people, and if it wasn't for, you know, Pat's Steaks and cheesesteaks, who's gonna come look at a bell with a crack in it?"For non-Philadelphians, a cheesesteak sandwich is thinly-sliced ribeye on an Italian roll with onions and a choice of cheese. Take note: The meat is thinly sliced, never chopped!"Because, I mean, God gave us teeth," Olivieri laughed. "I mean, it's a steak sandwich, it's not grind meat. If you want a chop cheese, you go to New York. So for me, it's sacrilegious to chop the meat."Olivieri says thinly-sliced meat is key to designing the perfect Philadelphia Cheesesteak sandwich. That, and (brace yourself) big globs of old fashioned Cheez Whiz.
