Laura Hoopes at the Christian Science Monitor recalls growing up pizza-deprived in Charlotte, North Carolina:
I had never heard of pizza when Jeanne first mentioned it, so I asked my mom if she knew what it was. She said no, but she had read about it in a recent magazine article. She took the magazine out and we read that it was a pie with tomato sauce, some kind of meat, and cheese.
Mom said she would try to make one. She produced a pie—in the sense of an apple pie—made with a crust containing tomato sauce and a meatloaf-like filling made with ground beef, which was topped with melted American cheese.
After real pizza finally came to town, her family had to rename their creation: Burger Pie, which sounds about right (or wrong). If you're curious, the recipe is included with Hoopes's recollections.
