As long as I can remember back, my mom always bought Appian Way box and doctored it up. First, she'd use two boxes at a time. She'd make the crust and bake it for about 5 minutes, remove it from the oven, then add the toppings. She'd add a can of Contadina tomato paste to the tomato sauce that came in the box, and a bunch of spices like oregano and basil, etc. She'd slather that on the half-baked crust. Then she'd add pepperoni, sausage, mushroom, green pepper and onion. And top it with the cheese and more cheese and plop on a few blobs of left over sauce. Back in the oven until it was melted and starting to brown. Pull it out, slice and serve, and, as remembered, burn the skin off the roof of your mouth because you couldn't wait for it to cool.
So that's the way we did it since the 60s until about two years ago, when they stopped making Appian Way. So we started making our crusts from scratch. Takes a bit longer, but tastes about the same to our memories.
