Heat the olive oil over medium-high heat in a deep large skillet, Dutch oven, or pot. When the oil is hot add in the ground beef and crumble it. When it's partially cooked add in the onion and garlic and season with salt and pepper. Continue to cook until the beef is cooked through and the onion has softened.

Sprinkle in the dried spices then pour in the crushed tomatoes, beef broth, and parsley. Reserve a little bit of the parsley for garnishing. Stir everything together then dump the pasta in. Stir so that the pasta is submerged completely in the sauce.

Bring to a boil then lower the heat to medium-low and simmer for 15-20 minutes or until the pasta is al dente. Stir often so that the pasta doesn't stick to the bottom of the pan. If the sauce gets too thick before the pasta has finished cooking, stir in ¼ cup of additional broth at a time.

Remove the pan from the heat and stir in the parmesan cheese and Greek yogurt (if you're using it) until it's fully incorporated. Taste for seasoning and garnish with extra parmesan cheese and parsley. Serve immediately.
