1. Heat the olive oil in a large skillet over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes.
2. Add the minced garlic and ground beef to the skillet. Cook until the beef is browned, breaking it up with a wooden spoon as it cooks, approximately 7-8 minutes.
3. Stir in the diced tomatoes, oregano, basil, cinnamon, salt, and pepper. Let the mixture simmer for about 5 minutes, allowing the flavors to meld together.
4. Add the orzo to the skillet, followed by the beef broth. Bring the mixture to a boil, then reduce the heat to low and cover. Simmer for 10-12 minutes, or until the orzo is tender and has absorbed most of the liquid.
5. Remove the skillet from heat and sprinkle the crumbled feta cheese over the orzo. Stir gently to combine.
6. Garnish with fresh parsley before serving, adding a vibrant touch and a hint of earthiness.

As you cook, remember to taste and adjust the seasonings to your liking. My abuela always said that cooking is an art, not a science, and it’s that spirit of experimentation that makes every meal special.
