Preheat the oven to 180°C.
Grate the carrot and potato using the fine side of a grater.
In a bowl, add the ground pork, grated carrot and potato, olive oil, salt, pepper, and oregano. Mix well until you have a uniform mixture.
Shape the mixture into meatballs.
Place the meatballs on a baking tray lined with parchment paper and bake for 35 minutes.
Remove the tray from the oven, turn the meatballs over, and bake for another 5–10 minutes, until they are golden brown on the other side as well.
Remove the tray from the oven and serve.
