In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add 1 diced onion and sauté for about 3-4 minutes until it becomes translucent.

Next, add 1 pound of lean ground beef, seasoning it with salt and pepper. Cook for about 5-7 minutes until the beef is browned and fully cooked.

Stir in 2 minced garlic cloves and 1 can of diced tomatoes, ensuring to drain excess liquid. Pour in 1 cup of beef broth and simmer on low for about 5 minutes.

Reduce heat to low and mix in 1 cup of Greek yogurt and 1/2 cup of grated Parmesan cheese until smooth and creamy.

Cook your favorite pasta until al dente. Reserve 1/2 cup of pasta water before draining. Toss the drained pasta with the creamy beef sauce.

Plate the dish and garnish with additional grated Parmesan cheese and fresh herbs if desired.
