Mmmm. I remember buying a slice of that kind of pizza from an outdoor stand while walking on Spaccanapoli towards the center of town most mornings while I was there. Better fast food than an Egg McMuffin! The sauce was so fresh, just lightly pureed tomato and oil. Once morning I dropped the slice and it flipped upside down onto my foot, and the sauce and oil squooshed into my sandal between my toes. L"Americana pazza gave the vendor a big laugh! Fortunately, he had some paper napkins for me to wipe my toes, which he found to be a sensual experience (I was a lot younger; and what isn't a sensual experience to a young Italian male?). My main concern was that they were my prized olive-colored leather sandals; but the oil didn't hurt the leather.
I am so fortunate today in my old age out here in the exurbs that a Neapolitan guy has built a pizzeria in the most unlikely German Protestant farm area, and he not only imports his ingredients from Napoli; he also imported the entire dome-shaped, tile-encrusted, wood-burning pizza oven. There is a huge stack of firewood outside the restaurant, which is always packed.
