Ok I'll bite. Not only for the webber but we did it on our Aldi BBQ over Christmas. Such a hit the kids asked for it again New Years Eve. Pizzas, I purchased Mission Oblong Pizza Bases (from Safeway), put on tomato paste, cheese, shredded ham, bacon, whisked egg and salami (for those that wanted). While one was cooking, I made up the next one. Took only a few minutes on a "biscuit" tray that I had raised off the grill on a trivet. Lid down on BBQ, perfect pizza, cut into four and everyone ate off their lap. No washing up. Brilliant.
