RE: Japanese Pizza
Red Baron makes a pretty good breakfast pizza, considering it's frozen and microwaveable. They are about 5 inches across, and are topped with eggs and a variety of breakfast meats and cheeses. Not as good as you could make yourself, but pretty convenient.
Repartee - other than the esoteric topping, what's the main body of Japanese Pizza like - ie the sauce, the crust, the cheese? If you ordered a pie untopped, would it more or less resemble something we are used to in the West?
