Preparing the Sauce
In a large skillet or pot, heat olive oil over medium heat. Add the tomato sauce and beef broth, stirring to combine. Allow the sauce to come to a simmer, creating a rich base for your cabbage rolls.
Cooking the Rolls
Carefully place the cabbage rolls seam-side down into the simmering sauce. Cover the pot and let them simmer over low heat for 45-60 minutes, or until the rolls are cooked through and tender. This slow cooking process allows the flavors to meld beautifully.
