In 1979, McDonald’s introduced Chicken McNuggets. They were a huge hit and every franchise across the country wanted them. But at the time McDonald’s didn’t have an adequate system to meet the demand. So Executive Chef Rene Arend was tasked with devising another new product to give to the unlucky franchises that couldn’t get enough chicken. Something that would keep them happy despite the shortages. Arend came up with a pork sandwich called the McRib.
