Roll out the pizza dough on a baking sheet. Mix the sour cream, cheese and diced ham in a bowl. Then distribute on the pizza dough. If you want, you can use other ingredients such as onions, mushrooms, peppers or mushrooms.
For the low-calorie variant, you can also use sour cream instead of sour cream, but then please whisk an egg underneath to make it more stable. When everything is on the tray, bake at 180 degrees on the middle rack for 20 minutes.
