Chick-fil-A Original Chicken Sandwich

Truett Cathy invented the pressure-cooked chicken breast on a buttered bun with two pickles in 1964, and Chick-fil-A has sold the exact same sandwich for 60 years. The restaurant generates more revenue per location ($8.1 million average) than any fast food chain in America — more than McDonald's, Starbucks, or Subway — while being closed every Sunday. The sandwich is so beloved that when Popeyes launched their competitor, the resulting "Chicken Sandwich War" generated $1 billion in media coverage for both brands. Chick-fil-A's brand loyalty scores consistently rank #1 in fast food. Two pickles. That's it.
