A mate of mine did ribs in his Weber while we were away and bloody hell they were nice.
Set up weber with normal grill flat plate and roasting trivet (anything to stop the direct heat from hitting the foil tray)
Turn on Weber to lowest setting
get Marinated ribs and put them in a foil tray
put a small glass (200mls) of water in the tray
leave for a 1 1/2 hrs and then turn over
put another small glass of water in and leave for another 1 1/2 hrs
Enjoy with a nice Ale or Cider
We added a bit extra Burbon BBQ sauce to the next batch and they were a bit tastier
The first lot we forgot about (drank too many ciders) and they cooked for about 4 hrs but were still fantastic.
While the stone is heating up we prep a few bases so as the first one comes out we slide a second one in while we start on the first, then repeat for number 3 and sometimes 4. Each pizza takes a little less then the first one as its nice and hot by then.
We only have the baby q so the pizzas are not huge but they only take about 12mins to cook I think so you can have a bit of a production line running.
