Combine all spice blend ingredients in a small bowl and mix well. Set aside. Heat olive oil in a large cast iron skillet or heavy-bottomed pan over medium heat.
Add diced onion and red bell pepper to the pan. Cook for 5-6 minutes until vegetables are softened and onion is translucent. Add minced garlic and prepared spice blend, cooking for another 30 seconds until fragrant.
Stir in tomato paste and cook for 1 minute. Add crushed tomatoes, salt, and pepper. Simmer for 10-12 minutes, stirring occasionally, until sauce thickens to a consistency that coats the back of a spoon. The sauce should not be watery.
Using a spoon, create 6 wells in the sauce. Crack each egg into a small bowl first, then gently pour into each well. Cover the pan and cook for 8-12 minutes depending on desired doneness: 8 minutes for runny yolks, 10-12 minutes for medium-set yolks. Sprinkle crumbled feta and fresh parsley over the top. Serve immediately with warm bread.
