01 - Heat the olive oil in a large skillet over medium heat. Add the onion and sauté for 2–3 minutes until softened.
02 - Add the bell pepper and cook for another 3–4 minutes, until the vegetables begin to soften.
03 - Stir in the garlic, cumin, smoked paprika, and chili flakes. Cook for 1 minute until fragrant.
04 - Pour in the diced tomatoes with juice. Season with salt and pepper. Simmer for 5–6 minutes, stirring occasionally, until the sauce thickens slightly.
05 - Make 4 small wells in the sauce, and crack an egg into each well.
06 - Cover the pan and cook for 5–7 minutes, or until the egg whites are set but yolks remain runny. Cook longer for firmer yolks.
07 - Remove from heat. Sprinkle with chopped parsley or cilantro and crumbled feta, if using. Serve hot.
