• Heat olive oil in a skillet, add chopped onion and cook until softened, seasoning with 1tsp of salt and pepper. Add garlic and cook for another minute.
• Brown the meat: Add minced meat and cook until well-browned and cooked through.
• Stir in tomato paste, Worcestershire sauce, paprika, tomato puree, and diced tomatoes. Simmer for 15-20 minutes to develop the flavors.
• Once the sauce is simmered, add cooked rice and combine well.
• Chop cabbage into bite-sized pieces. In a separate pan with olive oil, cook the cabbage over medium-high heat until wilted and partially cooked, seasoning with remaining salt.

Assembling and Baking the Casserole:

• Set the oven to 350 degrees Fahrenheit.
• In a baking dish, spread ⅓ of the meat sauce as the first layer. Top with ½ of the chopped cabbage. Repeat with another ⅓ of the sauce and remaining cabbage. Finish with the final ⅓ of the sauce on top.
• Cover the casserole with foil paper and bake for 30 minutes.
• Remove the casserole from the oven, take off the foil, and top with shredded mozzarella cheese. Bake uncovered until the cheese is bubbly and melted.
