Ingredients: 

 12 (or more) large cabbage leaves

For filling:

1 pound lean ground beef

3/4 cup cooked rice

 1 large egg

 1/2 cup finely chopped onion

 1 1/2 teaspoons sweet paprika

 1 1/2 teaspoons salt

 1 teaspoon pepper

 Sauce : 

 1 can tomato sauce

 1 can diced tomatoes, undrained

 2 tablespoons cider vinegar

 2 tablespoons cornstarch mixed with 2 to 3 tablespoons cold water, to thicken the sauce

I also like to eat them with a bit of yoghurt.
