Preheat the oven to 350 degrees F. Spray a 9-inch by 13-inch baking dish with non-stick cooking spray. It can also be made in a large oven-proof skillet with high sides (it's a deep casserole).
Heat a large high sided skillet or large Dutch oven over medium heat and add the olive oil. When the oil is warm (the surface will ripple), add the chopped cabbage and 1 teaspoon of salt. Sauté the cabbage, stirring occasionally, until it is just crisp-tender– about 8 minutes. Remove the cabbage to a plate and set it aside.
2 tablespoons olive oil, 1 small head green cabbage, 2 teaspoons kosher salt
Add the ground beef to the skillet and return it to medium-high heat. Cook, stirring occasionally, until the beef is almost browned– about 5 minutes.
1 pound ground beef
Add the onion and garlic. Cook for an additional 3-4 minutes, or until the onion is tender.
1 medium yellow onion, 2 cloves garlic
Add the diced tomatoes, tomato sauce, Italian seasoning, black pepper, and the remaining teaspoon of kosher salt.
1 14.5-ounce can diced tomatoes, 1 8- 8-ounce can tomato sauce, 2 teaspoons Italian seasoning, 1 teaspoon freshly ground black pepper
Remove the pan from the heat and add the rice and cabbage to the meat mixture. Stir to combine.
2 cups cooked rice
Transfer the casserole to the prepared baking dish and add the cheese to the top of the casserole.
2 cups shredded cheese
Bake for 20-25 minutes, or until the cheese is melted and bubbly. Garnish with sliced green onions or chopped parsley and enjoy.
