stryped,
If you are talking about the sequence of dressing the pizza, you have a lot of latitude there. For example, for the pizza in question, my recollection is that I put the sauce down first, followed by the sausage, some of the pineapple, the cheese, more pineapple, and finally the pepperoni slices on top of the cheese. However, sometimes I put part of the cheese on top of the sauce, followed by the toppings (such as the sausage and pineapple), more cheese, maybe some more pineapple, and the pepperoni slices on top. I almost always put the pepperoni slices on top, although some prefer to put the slices under the cheese. I usually try to keep the sausage, or most of it, under the cheese to prevent it from drying out and getting hard and crispy. It's all a matter of personal preference.
