Preheat the oven to 350°F. Spread the cabbage across the bottom of a 9x13 dish. In a large skillet, over medium heat, cook the ground beef along with the chopped onion.

Drain any grease from the pan and add the uncooked rice, chili powder, garlic powder, salt, and black pepper to the skillet with the meat. Add the crushed tomatoes and stir to combine. Spread the meat mixture over the cabbage in the baking dish.

Mix together the tomato sauce, sugar, and vinegar and pour over the meat and cabbage. Cover with foil and bake for 90 minutes. Uncover and let rest for 5-10 minutes before serving. Enjoy!
