Heat olive oil in a large skillet over medium heat. Add onion and bell pepper and cook until softened, 5-7 minutes.
Stir in garlic, cumin, paprika, and chili flakes. Cook for 1 minute until fragrant.
Pour in crushed tomatoes. Season with salt and pepper. Simmer for 10-15 minutes until thickened.
Make 4 wells in the sauce and crack an egg into each. Cover and cook for 5-8 minutes until whites are set but yolks are still runny.
Garnish with fresh parsley or cilantro and feta cheese. Serve immediately with crusty bread.
