Creating this Easy Cabbage Casserole is a fun and straightforward process. Follow these steps to achieve a satisfying meal:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Sauté the Onions and Garlic: In a large skillet, heat olive oil over medium heat. Add the chopped onion and minced garlic, cooking until softened, about 3-5 minutes.
3. Cook the Ground Meat: Add the ground beef or turkey to the skillet, breaking it up with a spatula. Cook until browned and cooked through, about 7-10 minutes. Drain any excess fat.
4. Combine Ingredients: In a large mixing bowl, combine the browned meat, chopped cabbage, cooked rice, diced tomatoes (including juice), oregano, salt, and black pepper. Stir until everything is well mixed.
5. Prepare the Casserole Dish: Grease a 9×13-inch baking dish. Pour half of the cabbage mixture into the dish, spreading it evenly.
6. Add the Broth: Carefully pour the beef or vegetable broth over the cabbage mixture.
7. Layer the Cheese: Sprinkle half of the shredded cheese over the cabbage mixture, then add the remaining cabbage mixture on top.
8. Top with Cheese: Finish by sprinkling the rest of the cheese over the top of the casserole.
9. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the cheese is bubbly and golden brown.
10. Garnish and Serve: Remove from the oven and let it cool for a few minutes before sprinkling with fresh parsley, if desired. Serve warm.
