First, cut the rolls lengthwise and place the halves cut-side up on a baking sheet. Distribute the cooked ham and salami evenly between the rolls. Add a generous spoonful of sour cream to each half. Top with the grated cheese for a delicious topping. Season to taste with salt, pepper, garlic, and paprika. If you like, you can mix the toppings a bit on the rolls to ensure all the flavors blend together. Preheat the oven to 200°C (400°F) and place the baking sheet with the pizza rolls inside. Bake for 10-15 minutes, until the cheese is nicely melted and lightly browned. Enjoy the pizza rolls!
