Preheat your oven to 350°F (177°C) and grease a 9'x13' casserole dish with avocado oil.

In a large skillet, brown 2 pounds of ground beef with salt, black pepper, and Hungarian paprika for 8-10 minutes.

In a mixing bowl, combine a 29-ounce can of tomato sauce with 3.5 cups of beef broth, then mix in the chopped cabbage, diced onion, and 1 cup of uncooked long-grain white rice.

Transfer the mixture to the greased casserole dish and cover tightly with aluminum foil.

Bake the casserole in the preheated oven for 1 hour, then stir and check seasoning.

Remove foil and continue baking uncovered for an additional 30 minutes.

Let the casserole rest for 10 minutes before serving.
