You can also put it on pre-cook, but if you do, it works best to put it under the cheese instead of on top. Then it gets warm but retains enough juice.
And more importantly, it's wasted with the sweet ham, better with salty pepperoni (or since you already have the salty olives, savory chicken) and jalapenos!
Wanna hear a "real" pizza crime from a (former) fellow professional? Basil pesto base, chicken, tomato, sliced strawberries, and a honey drizzle. Don't knock it until you try it (strawberries optional, but exceptional. And red onion optional as well).
