The joys of working at a pizza place meant I got to make whatever I wanted, albeit out of Pizza Hut ingredients..
Typically went for:
Stuffed Crust, Cheese/Spinach/Capsicum/Pineapple + Oregano. Sometimes with bacon, and other times with taco seasoning (when we did Mexican pizzas).
Pizzas with ranch sauce were supposedly pretty good, considering (although I never had one).
