PEET-sa? What is this witchcraft?

If you think everything in your life has always been around, think again. My parents were full-on adults before they'd first tasted pizza, and Mom always reported that my dad took one bite and spat it out. 

If he'd had this 1947 recipe, I kind of understand. Biscuit mix, cold cuts, sliced cheese and ketchup! 

They also have to tell us how to pronounce "peet-sa," much like Taco Bell in the 1980s actually had pronunciations for "taco" and "burrito" on their menu boards. ("Tah-COH?")
