Had best success yet last weekend with pizza on the egg. The difference was useing the .94 cent grill topper screen that Wal-Mart sells. I believe it know in the trade as expanded aluminum. Made semalina dough in breadmaker, rolled fairly thin. Did three versions: white pizza w/ caramelized onions and goat cheese, barbequed chicken w/ barbeque sauce and Italian three cheese blend and finally blue cheese with caramelized onions. Put pizza on lightly oiled screen and cooked at about 450 degrees (lid closed) for 4-5 minutes. Crust was perfect and did not stick to screen at all. I felt these came out better than useing the pizza stone.
