I tried it as well, and was similarly disappointed.

The "topping" part of the pizza is a lot smaller, and the meatball "cheeseburgers" had no flavour because there was no sauce under them (tomato paste or bbq sauce, from the rest of the pizza).
When I put bbq sauce with the "burgers", they weren't too bad... but not as awesome as I had hoped.




Now this... is a Cheeseburger pizza...
