Hmmm...are you going to precook the crust and then top it and finish it? I think I would do it that way myself. Put the dough in a cold pan, bake it at 425 or so for about 20 minutes (my timing might be way off here, so check the recipe) then pull it out and fill it up and put it back in for about 10 - 15. That would be my best guess.
