A couple of pages back, Pizza Maker provided an excellent and detailed rundown of Papa Gino's recipes, ingredients and processes. I have a few things to add based on my own experience (5 year employee) as a driver, grill/deli and pizza person there...
My tenure was late 90s. Our location had gone to the commissary mode for the duration of my tenure.
Would arrive every couple of days, on rolling racks, in shallow square/rectangular tubs with lids. The newest dough would arrive very cold and even near frozen. We would push the racks into the walk-in for a day or so, then they would be removed so they could proof for about a day near the pizza prep area.
When ready, before each meal shift dough would be hand-tossed into shape and placed on a screen/parchment combo. If done shortly enough before meal time, these shells would sit on a small rack on the prep counter; otherwise, they'd go into a rolling rack with some plastic sheeting to preserve moisture.
NOTES: parchment was corn-mealed heavily; dough had a grayish tint when cold/frozen; dough was VERY consistent in its behavior -- you could use your watch to know when it was at the perfect temp for tossing
Sauce came in 5-lb or so thick Mylar plastic food pack bags. Minimal spices. Clean, fresh crushed tomato, maybe a bit of salt and garlic. No oil (or none detectable). No green spices.
5-lb bags. Seemed to be a mozzarella-provolone blend with added green spices i.e. oregano, basil. I'd bet you $5 it was part-skim mozzarella because of the firm bite and the way it melted. Probably 5 oz. on a small, 8 oz. on a large.
Rotating shelves, 525F at least, pizzas cooked on parchment. About eight minutes for cheese or roni - 10-12+ for specialty with any type of veggie load.
What I've seen about PG's sauce on here does not jibe with my own experience. Think Don Pepino's with less or no oil. (Side note: PG's pasta dish sauce was quite different, very rich and spicy, very thick. Very good too.)
Sam's Club sells a very nice 50-50 Mozzarella-Provolone blend cheese. There are no herbs but you could add them easily. While not a match, I'd call this a close match to the PG's cheese I remember.
