First of all, a salty meal like pizza will always pair well with a sweet tangy flavor profile, like oranges. Fresh oranges roasted with olive oil and sea salt until it's caramelized is one of the world's true delights. Second, you can't hate on a pizza topping that is actually good for your health. Oranges are a great source of Vitamin C, potassium, and fiber, helping regulate blood pressure and ease digestion. If you order a orange pizza for a group, there are likely others who will refuse to eat any, which just means there's more for you. Basically it's impossible eto go wrong getting a orange pizza.
