I have a bread machine, which makes pizza dough a trivial process. The sauce is easy to whip up in large quantities and chill between uses, though I tend to just buy a jar of something decent. After that, it's just a matter of using whatever ingredients are handy in the fridge at the time. Pizza-making is not really complicated.
Order of operations matters, though. I prefer to put the cheese on top of everything else, but sometimes you want certain ingredients to be a little broiled. And if you use a lot of fresh veggies, the pizza will tend to get a little watery.
