We’ve done the same thing for a good 15 years here, and I know that the method has critics (and with good reason at some points).
We simply make up the pizza inside a buttered aluminum pan, deli-wrap with the earlier mentioned deli wrapper, label and stick in case to sell. I hear a lot of people say it doesn’t work as well because the bright aluminum bottom doesn’t cook the pizza correctly, but because of the good coating oil, it crisps the crust while baking the rest very well, it is a good pan pizza texture and flavor. Crispy crust, no gumline, good stuff.
Most families love it, because there are no akward moments at all. Unwrap plastic, put in oven. A hotpad to remove it, it can be cut and served right from the tray, or easily removed with a spatchula. Seniors love it too, for the same reason.
