1. **Cook the Ground Beef**: In a large skillet, heat the olive oil over medium heat. Add the ground beef and cook until browned, breaking it up with a spatula. Drain excess fat if necessary.

2. **Add Aromatics**: Stir in the diced onion and cook until softened, about 3-4 minutes. Add the minced garlic and cook for another minute until fragrant.

3. **Add Cabbage**: Add the chopped cabbage to the skillet. Stir well to combine. Cook for about 5-7 minutes, until the cabbage starts to wilt.

4. **Add Tomatoes and Seasonings**: If using diced tomatoes, add them to the skillet along with the beef broth. Stir in paprika, salt, pepper, and thyme.

5. **Simmer**: Cover the skillet and let it simmer for about 15-20 minutes, stirring occasionally, until the cabbage is tender and the flavors meld together. If it seems too dry, add a bit more broth or water.

6. **Serve**: Taste and adjust seasonings as needed. Serve hot over cooked rice or pasta, if desired.

Enjoy your hearty meal!
