I'm sure you have made french bread pizza, English Muffin pizzas, etc., but this is how I make pizzas for my two kiddoes (i.e. the husband and the actual child, lol) and they love it. Just top as you would any other pizza, and bake toast according to directions on the box.
It's not as fattening as you would think, and you could always go a leaner route, with a leaner meat, reduced fat cheese, etc.. and it sure beats shelling out an unGodly amount of money, ordering pizza, which I loathe. (It really is highway robbery.)
All stores have their own brand of this stuff and it's super cheap.
Our Wal-Mart has pizza sauce for 98 cents (every day) and it does not have High Fructose Corn Syrup in it...
