1. In a large skillet over medium heat, cook ground beef until browned, breaking it apart as it cooks. Drain any excess grease if needed.

3. Stir in tomato paste and cook for 1 minute to deepen its flavor.

4. Pour in crushed tomatoes, Italian seasoning, salt, and pepper. Simmer the sauce for 5 minutes.

5. Add dry orzo to the pan and stir to combine. Add water or broth, and let it simmer gently until the orzo is tender, stirring occasionally.

6. Lower the heat and stir in heavy cream and Parmesan cheese until creamy and thickened.

7. Adjust seasoning to taste and serve warm, garnished with extra cheese or herbs if desired.
