Prepare ingredients: Drain sardines or cook fresh fish and flake into pieces. Hard-boil 4 eggs, peel and slice. Dice bell peppers, tomatoes, and onions. Set aside corn, peas, and olives.

Make the broth: In a large saucepan, heat olive oil over medium heat. Sauté diced onions and minced garlic until softened, about 3 minutes. Add diced tomatoes, tomato paste, salt, black pepper, and paprika. Cook for 5 minutes, then add 3 cups of water. Bring to a boil and simmer for 10 minutes.

Prepare cornmeal mixture: In a large bowl, gradually add the hot broth to the cornmeal flour, stirring constantly to prevent lumps. The mixture should be moist but not soupy. Let it rest for 5 minutes to absorb liquid.

Grease the cuscuzeira: Generously grease a cone-shaped cuscuzeira or bundt pan with olive oil or butter.

Layer the cuscuz: Start with a layer of cornmeal mixture at the bottom. Add decorative arrangements of egg slices, bell peppers, tomatoes, and olives on the sides. Continue layering cornmeal, flaked fish, peas, corn, and remaining vegetables, pressing gently to compact.

Steam the cuscuz: Cover the pan tightly with aluminum foil or the lid. Place in a large pot with 2 inches of simmering water. Steam for 35-45 minutes until firm and cooked through.

Rest and unmold: Remove from heat and let rest for 10 minutes. Run a knife around the edges, place a serving platter on top, and carefully invert to unmold. Garnish with fresh parsley and serve.
