Add tomatoes, vegetable broth, cumin, paprika, oregano, and salt and pepper; simmer for 20 to 22 minutes or until thickened.Crack eggs evenly on top of sauce; cover and cook for 6 to 8 minutes or until whites are set and yolks are thick but runny (if you like firmer yolks, cook for 1 to 2 minutes more). Sprinkle with parsley and feta cheese and serve with warm pita bread.
