Heat olive oil in a large skillet over medium heat. Add onion and bell pepper, cook 5-6 minutes until softened.
Add garlic, cumin, smoked paprika and cayenne; cook 1 minute until fragrant.
Stir in crushed tomatoes and sugar; season with salt and pepper. Simmer uncovered 10 minutes, stirring occasionally, until slightly thickened.
Use a spoon to make 6 small wells in the sauce. Crack an egg into each well.
Cover the skillet and cook 6-8 minutes, until egg whites are set but yolks are still runny (longer for firmer yolks).
Sprinkle with feta and fresh herbs.
Serve hot straight from the skillet with crusty bread or pita for dipping.
