Pizza, ZA, pie, and sometimes even flatbread

I cant tell you if i remember my first words, My first day of school, first day i rode a bike by myself or even the first day i may or may not have lit the living room carpet on fire. What i can remember is my first slice of pizza. I cant tell you why this gastronomically simple dish is so revered in almost every part of the world. I just know that its like being back home for me. Its something i can eat 3 times a day and still crave a slice the next day.
