Chattius, you might be interested to know that what you guys make is indeed a type of pizza. It's a variant on what is known as a "white pizza", where you use an alternative base such as sour cream or oil & garlic instead of tomato sauce (because oil & garlic were for a very long time much easier for people to get than tomatoes, which were hilariously considered as being poisonous by people outside of Italy). This type of pizza originated in Greece a very long time ago (the original was basically what is in your picture, and they used Feta/goat cheese) and since has spread everywhere from Turkey and the USA to China. You'll find regional variations on the sour cream based pie in Hungary, Spain, Portugal, and the USA.
