The Philly Cheesesteak made its official debut in 1930, when a South Philadelphia hot dog vendor decided to put some beef from the butcher on his grill. A passing taxicab driver smelled the delicious aroma and asked for his own steak sandwich. Rumor of the new lunch creation spread quickly, and by the following day, cabbies from all over the city came flocking to the same hot dog stand, demanding the delicious steak sandwiches. Thus began a Philadelphia tradition that is now enjoyed around the world. Our Kinder's Philly Cheesesteak offers authentic sliced and seasoned steak, grilled to perfection, topped with melted cheese and served in a classic hoagie style roll. The ideal balance of flavor and tenderness in an easy heat-and-serve sandwich that is sure to satisfy with every bite. Full freshness guaranteed until date shown if stored unopened and frozen.
