Prepare the Cabbage:
Bring a large pot of water to a boil.
Remove the core from the cabbage and blanch the whole head in boiling water for 2-3 minutes.
Gently peel the leaves and set aside.
Make the Filling:
In a large bowl, combine the ground beef, ground pork, cooked rice, onion, garlic, egg, salt, pepper, and paprika.
Mix well until all ingredients are evenly distributed.
Assemble the Rolls:
Place a spoonful of the filling onto the center of each cabbage leaf.
Fold the sides of the leaf over the filling and roll tightly, securing the ends.
Prepare the Sauce:
In a large skillet or pot, heat olive oil over medium heat.
Add the tomato sauce and beef broth, stirring to combine.
Bring the sauce to a simmer.
