Honestly this doesn't sound like it would taste all that bad. Thick crust, tomato sauce, green bell pepper, fried salami, and Velveeta cheese? That's gonna be pretty tasty. Calling it pizza might be the biggest issue, maybe something like open faced pepper sandwich would be better.
Urgh, here in Canada they tried to trick us with "delux" kraft dinner. Velveeta is so bad that I avoid name brand KD to this day due to one time over a decade ago. How in the artificial fuck do americans eat that stuff?
Yet its more expensive then the normal cheese mix here. Its vile stuff that makes melted plastic seem edible. The "cheese" at 7-11 (that contains no dairy) is 1000 times more cheese then it and is still avoided by most sober people.
