1. Heat the olive oil in a large pot over medium-high heat. Add the beef cubes, searing them until browned on all sides. This should take about 5-7 minutes. Remove the beef and set aside.
2. In the same pot, add the chopped onion and garlic, cooking until the onion is translucent and fragrant, about 3 minutes.
3. Pour in the red wine, if using, and let it simmer for about 2 minutes, scraping up any browned bits from the bottom of the pot for extra flavor.
4. Return the beef to the pot and add the beef broth, diced tomatoes, tomato paste, oregano, cinnamon, salt, and pepper. Stir well to combine.
5. Bring the mixture to a boil, then reduce the heat to low. Cover and let it simmer gently for about 1 1/2 hours, or until the beef is tender.
6. Preheat your oven to 350°F (175°C). Transfer the beef mixture to a large baking dish, stir in the orzo, and cover with foil.
7. Bake in the oven for 30 minutes. Remove the foil, sprinkle with Parmesan cheese, and bake for an additional 10 minutes until the cheese is melted and golden.
8. Garnish with freshly chopped parsley before serving. Enjoy!

Remember, cooking is an art, and like my abuela taught me, it’s okay to follow your senses. If the aroma calls for a bit more oregano or a sprinkle of nutmeg, go for it!
