Preheat oven to 350°F (170°C). Spray a large 13 "x10" or 13 "x9" casserole dish with non-stick spray.
Heat a large skillet or saucepan on medium heat, add oil, and follow with the ground beef and pork. Cook, breaking it apart as it cooks, until it's browned and cooked through (5-7 minutes). Remove browned beef and set aside.
In the same saucepan, add another tablespoon of oil. Followed with onions and cook over medium heat until the onion is translucent (4-5 minutes).
Add the minced garlic, thyme, Creole seasoning, and paprika, and cook for about 2 minutes more.
Then, return the beef mixture to the pan with the diced tomatoes with juice, tomato sauce, rice, water, Worcestershire sauce, and bouillon powder. Season to taste with salt and pepper.
Bring to a boil and let it simmer until slightly thickened (15-18 minutes).
While the sauce simmers, add 1-2 tablespoons of oil to a large skillet or Dutch oven, add the cabbage, and cook over medium-high heat until the cabbage is tender. It doesn't need to cook much because it will continue cooking in the oven.
Season cabbage with salt and freshly ground black pepper. Remove and layer in the bottom of the casserole dish.
Place the meat and rice mixture over the cabbage and press if needed.
Cover the casserole tightly with foil and bake for 35-40 minutes.
Carefully remove the foil with oven mitts and sprinkle the cheese over the casserole if desired.
Bake uncovered for 7-10 more minutes or until the cheese melts. Remove from the oven, let it cool slightly, and serve hot.
