Step 1

In a large skillet, heat the oil. Add the onion and fennel and cook over moderately high heat, stirring, until softened, 3 minutes. Add both chiles and the bell pepper and season with salt. Cook over moderate heat, stirring, until softened, about 8 minutes. Add the garlic, harissa and paprika and cook, stirring, until fragrant, 1 minute. Add the tomatoes and water and simmer over low heat until the sauce is thickened, 10 minutes.

Step 2

Crack the eggs into the sauce. Cover and cook over moderately low heat until the whites are firm and the yolks are runny, 5 minutes. Spoon the sauce and eggs into bowls and sprinkle with the parsley and crumbled feta. Serve right away.
