Cook the Pasta: Bring a large pot of salted water to a boil. Add pasta and cook until al dente, about 8-10 minutes. Drain and set aside.

Brown the Beef: Heat olive oil in a large skillet over medium heat. Add ground beef, breaking it apart, and sauté until browned and no longer pink, about 5-7 minutes. Drain excess fat.

Sauté Aromatics: Add diced onion and minced garlic to the beef. Cook until onion is translucent and garlic is fragrant, about 3-4 minutes.

Combine Ingredients: Stir in diced tomatoes, then add cooked pasta, Greek yogurt, and Italian seasoning. Mix thoroughly until well combined.

Add Cheese: Stir grated Parmesan into the skillet, allowing it to melt into the sauce. Season with salt and pepper to taste.

Serve and Garnish: Transfer to plates or serving dish and garnish with additional Parmesan or fresh herbs as desired.
