You could try stirring the curd the entire time in step 5, but fresh Mozz. is going to be wetter than anything you buy at the store. I always sauté all the other veggies that I put on the pizza, before I assemble it, and cook the crust, before assembling the pizza, that way most of the water from the veggies and crust are already cooked out, and you just have to leave the assembled pizza in the oven long enough to melt the cheese and blend the flavors.
