The company wouldn't give a date for the sandwich's return.
Popeyes isn't the only fast-food chain with buzz around a sandwich. Burger King launched the Impossible Whopper, made with plant-based meat from Impossible Foods, four days before Popeyes introduced its chicken sandwich. The Impossible Whopper's success may have contributed to the company expanding. CNBC reported the company filed an application in the European Union to be able to use a genetically modified ingredient called soy leghemoglobin, which makes the brand's plant-based meat taste like the real thing.
