In a large bowl, mix the minced meat with rice, onion, salt, pepper, and paprika.
Take a sour cabbage leaf and place a spoonful of the meat mixture at the bottom. Roll the leaf up, tucking in the sides to enclose the filling.
Repeat the process until all the leaves and filling are used, stacking the rolls in a large pot.
Cover the sarmas with more sour cabbage leaves and add water to cover them completely.
Bring the pot to a boil, then reduce heat and simmer for about 2 hours or until the rice is cooked and flavors are combined.
Serve hot with crusty bread.
