Top each schnitzel with a slice of cheese and a slice of ham. Roll up from the narrow side, secure with roulade clips or wrap with twine. Season lightly with salt and paprika.
Mix the tomato paste with water.
Place the roulades in the soaked Römertopf, pour in the liquid. Place in the cold oven and stew at 220 degrees top / bottom heat for 75 minutes.
Ham and cheese give off some of their flavor to the meat, so don`t season too much.
