I had coupons for Digorno's, so I got 2. They are absolutely terrible. Regular price is about $7. I can get 10 slices of Ohio Valley style for that! That said, I love Tombstone pizzas. When I was a kid, my grandmother would make me a whole pie for a snack before dinner. You have to make the crust crunchy, but not burn the cheese. The Stouffer's French bread white pizzas are good too.
There's a local pizza shop here (Augustines) who sells frozen pizza in grocery stores and supposedly Heinz Field in Pittsburgh. Sweet sauce, and it's pretty good. Odd crust, as its thick and flaky kind of like a deep dish, but not the same.
Weirdest cooking instructions I've ever seen though. I'm doing this by cooking it once, so it's probably a bit off. Thaw pizza, preheat oven to 400, put pizza on cookie sheet, pour olive oil on top, bake for 10 min, cut into slices, bake for 10 minutes longer.
One other thing. I was at a bar once where they made pizza burgers. Big deal right? Burger with mozzarella, sauce and pepperoni. This place used those frozen square slices as the bun for a plain burger. Toppings were added to the burger. It was very, very good!
