In a large pan with high sides or a Dutch oven, heat the oil over medium-high heat. Add the ground beef, chopped onion, and orange bell pepper. Cook until the beef has browned and the onions are soft and translucent.
Now, add the chopped garlic to the pan and sauté for an additional minute. The delightful aroma will fill your kitchen!
Next, stir in the fire-roasted diced tomatoes, smoked paprika, dried oregano, garlic powder, onion powder, salt, and pepper. Gently fold in the chopped cabbage. Cover the pan and let it cook for about 15-20 minutes or until the cabbage is tender.
Once the cabbage reaches that perfect tenderness, you will top that colorful mixture with shredded cheddar/Jack cheese. Cover the pan again and allow the cheese to melt, creating a delicious, gooey topping.
Serve the Low Carb Unstuffed Cabbage Casserole hot, and relish in the warm, comforting flavors of this wonderful dish!
