I buy cheap pizza and add my own ingredients. For the price it takes to add "ham" to a pizza, I can buy a package of tasty cold-cuts and use it on 3-5 pizzas, plus sandwiches. I don't buy anything with olives, as I always have them in case the need for a martini strikes. Same goes for cheese, extra sauce (red sauce + oregano + basil + garlic powder + crushed red pepper), veggies, etc, etc. This way, I have tons of tasty things that I can use for many different meals, my toppings are mostly very fresh, and I can make whatever I want.
Now that I think about it, I'd be better off just making all of my own pizzas, except pizza crust fucking costs more than it does to just buy frozen pizzas and I don't have the time to bake pizza crusts.
