When sold with a drink and a cookie, the round sandwich formed what was known as a Kids' Pak for just under $2.50. Another version of the Kids' Pak was advertised for $3.69 and included the round sandwich, fruit punch, and a Fruit Roll-Ups snack served with a toy. "I used to order them all the time as a kid," wrote one Redditor. But children weren't the only ones enjoying this treat - some recall eating the sandwiches as college students or with their grandparents. Now, however, the item has become one of those fast food classics we may never get back.
